Blue Diamonds Hold The Earth's Secrets

Photo: IFLScience

Full disclosure: I'm not a scientist and I don't want to take credit for the work of others. All I can do is read a bunch of sources, then put some of the facts together so you don't have to read all those sources yourself. The following is a paraphrasing -- the Turner "CliffsNotes" -- from several sources on a subject I love covering ... gemstones and jewelry! In today's blog, let's learn more about blue diamonds!

Only 1 out of 200,000 diamonds are blue. Like all other diamonds blue diamonds were formed billions of years ago when the element carbon was exposed to extreme heat and pressure deep in the earth's mantle. Clear (a/k/a white) diamonds are pure carbon. If traces of boron contaminate the carbon during its growth, a blue diamond is created. The industry calls all colored diamonds fancy diamonds.

Scientists are intrigued by the origin of blue diamonds because they hold many of the earth's secrets. Once an enchanting mystery, gemologists now think they understand how these extremely rare blue gemstones came about. It also gives us clues about the evolution of the earth, itself. After the Gemological Institute of America conducted studies using lasers to uncover impurities (minerals) that got trapped inside blue diamonds, the experts started to assemble a picture of how and where blue diamonds were formed.

Based on their discoveries, scientists know that blue diamonds were formed much deeper in the earth (below 410 miles) than other diamonds (formed between 90 miles - 125 miles below the earth's surface). It is believed that boron in the ocean floor "was pushed down when plates that make up the Earth's crust collided," making the diamonds appear blue. (According to researchers, boron lets the diamonds "absorb some red light, so the diamonds look blue.")

Diamond deposits formed very deep within the earth eventually reach the surface by volcanic eruptions.

Now we know how some of the big rare blue gemstones such as the Hope Diamond and Oppenheimer Diamond were born. Billions of years ago Mother Nature had to come together in just the right way to produce them and for humans to find and have them all these years later.

Heart of Eternity
Both blue and white diamonds are graded using the 4 Cs: cut, clarity, color, and carat. But!
 Blue diamonds are so rare and in demand for their beauty, that they tend to cost more per carat than white diamonds. The blue diamonds that become well-known and fetch millions of dollars at auctions invoke excitement and fame because their unique size, color, and clarity are so rare.

Mouawad Blue
As it happens I don't have any blue diamond jewelry. Diamonds are valued for their sparkle and brilliance. Colored gemstones will have less sparkle than white diamonds. Their value is determined by the vividness, tone, and saturation of their color. Vivid blue diamonds are so rare and expensive that we get less for the money than if we buy white (a/k/a clear) diamonds. I have never been tempted to buy blue diamonds because blue diamonds aren't very budget-friendly, and I don't want to spend a lot of money on faint or tiny blue diamonds! I'd rather compromise by buying a commercial-grade sapphire.

The good news is scientists can make blue diamonds in a lab. Laboratory diamonds are grown in an artificial setting that mimics how diamonds grow naturally below the earth's mantle. Lab-grown diamonds are getting better and more plentiful all the time, which is lowering the prices per carat of all diamonds! 
The color of these blue diamond earrings looks enhanced. You never see such dazzling blue diamonds in jewelry display cases! They did, however, inspire me to write the blog. Wouldn't we love to own real blue diamond earrings just like them? Of course we would!:)💙🔵

Diamond Prices Are Crashing

As much as I love jewelry I've always known the price of gemstones is arbitrary to a great extent. Jewelry is as much of an overpriced luxury item as Hermes handbags, Manolo Blahnik shoes, or Dior pants and coats. They cost what consumers are willing to pay for them. Never think of luxury items as investments but to be enjoyed as things of beauty only. The value of luxury goods is driven by want not need. If you covet investments, take your money to an investment firm to buy stocks, bonds, and mutual funds, where you'll earn returns on your portfolio. You're lucky to break even by reselling luxury goods after you subtract a 15% - 20% commission.

So I'm happy to report an exciting development in the diamond market! In 2023 diamond prices are tumbling down -- about 23% for 1-carat stones and about 15% for 3-carat stones -- according to experts who watch diamond prices such as That Guy Osiris, an ex-diamond trader who has a YouTube channel. 

The reasons for the decline in diamond prices are several: 

(1) Monopoly diamond sellers such as DeBeer aren't as powerful as they once were in setting diamond prices high combined with limiting the supply of gemstones on the market. 

Photo: istock
(2) Nowadays the demand for diamonds is less. Not every bride in 2023 desires an engagement ring. Some wish to put their $7,000 - $15,000 earnings elsewhere such as for a downpayment on a house or car. Millennials are more interested in spending on travel and experiences than buying diamond rings.

(3) A main reason why the price of diamonds is sinking is the greater acceptance by the public of lab-grown diamonds which cost about 1/3 less than diamonds mined in nature. Diamonds created in a lab are chemically and optically identical to natural diamonds.

(4) The process of making laboratory diamonds is getting better and cheaper all the time, and more companies including jeweler James Allan are offering them. According to Liberum Capital Markets, about 25% to 35% of diamonds sold to customers today are lab-grown diamonds.

5) That Guy Osiris says that industry leader DeBeers is responding by discounting its prices for 2 - 4 carat rough natural diamonds. Recently prices for uncut natural diamonds have dropped from $1,400 a carat to $850 per carat to be competitive with lab-grown diamonds.

All of this is a win, win, win for customers! If diamond prices keep falling, one day I'll be able to afford my fantasy 4-carat stud diamond earrings (that's 2-carats each ear, sister!!), my 20-carat diamond blingy tennis bracelet, and my 5-carat diamond solitaire ring ... no engagement needed!

I don't care one iota about the lesser monetary value of lab or natural stones as long as I'm not charged for it. Just give this glitter-loving girl her diamonds! I'll start with that big brilliant round diamond at the top of the blog and the pear-shaped diamond ring at the bottom! We
 can add my fantasy diamonds to my collection later.😉😂

If in the future diamonds cost less, would you value them less?

The Regent Diamond Sits In the Louvre

Photo: go here  - Note the size of the diamond when holding it and look at the perfectly manicured nails! Both are amazing!
The Regent Diamond is the 7th largest of the D-grade colorless diamonds in the world. It is also one of the purest and most brilliant of the known large diamonds. Gemologists think it was mined in Golconda, India between 1698 and 1701. In 1701 an Indian diamond merchant named Jamchand sold the 410-carat uncut diamond to Thomas Pitt, the Governor of Madras, who sent it to England hidden in the shoe of his son, Robert Pitt, where it was perfectly cut by a diamond cutter called Harris, into an internally flawless 140.64-carat brilliant cushion-shaped diamond.

Eventually, Pitt sold the diamond to Philippe d’Orléans, regent for Louis XV, the 5-year-old grandson of Louis XIV of France, which is how it acquired its name. In 1723 the Regent Diamond was set in the coronation crown of King Louis XV. It was reset in 1775 in a new coronation crown for the ill-fated Louis XVI. His wife Queen Marie Antoinette also wore the diamond attached to a black velvet hat. During the French Revolution, the Regent Diamond was stolen (along with the Crown Jewels) but it was later found in a Paris attic.

In 1812 Emperor Napoleon Bonaparte took possession and had the diamond mounted in his sword. After he was defeated at Waterloo and exiled from France, his 2nd wife, Archduchess Marie Louise smuggled the diamond to her native Austria, but her father, Emperor Francis I, returned it to the French Crown Jewels where the Regent Diamond was set in the crowns of France's 
Louis XVIII, Charles X, Napoleon III, and a Greek style diadem of Empress Eugenie, wife of Napolean III. After France once again dethroned and expelled its royal family, the Regent Diamond ended up at the Louvre Museum in 1887. During the Nazi occupation, the Regent Diamond was sent (along with the Mona Lisa)  to the Loire Vally where it was hidden in the plaster sealing the marble of a fireplace at the Chateau de Chambord, returning to the Louvre after the liberation of Paris and the unconditional surrender of Germany in 1945. The gem is now owned by the French state. 

Cushion cuts have more fire (i.e., colored light) than other diamond cuts. Today the Regent Diamond, an ideal cut, bluish-tinted stone, is on display at the Louvre for public viewing. What an adventurous journey ... with a happy ending. Home sweet home!

India’s Famed Koh-i-Noor Diamond

Photo: Baunat
India's famed Koh-i-Noor (meaning "Mountain of Light") Diamond is one of the most extraordinary diamonds in the world. First mentioned in history in the 14th century, it was owned by the ruling maharajahs of India, but after bloody battles, the diamond became a spoil of war to various Sikh, Mogul, and Persian rulers.

Prince Duleep Singh
It was given as a gift to Queen Victoria during the colonial era when the powerful British East India Tea Company annexed Punjab (then in India, today also in Pakistan) in 1849 forcing its 11-year-old ruler, Prince Sir Duleep Singh, into abdicating and surrendering his lands and prized diamond via the Treaty of Lahore. The legendary diamond was singled out as a symbol of conquest.* The British authorities also separated the boy from his mother, refusing to let him see her for 13 years. They brought him to England where he was educated, given estates, a palace, and the privileges that reflected his rank as a Prince and Maharaja, plus a yearly pension (of $3,145,248 in today's value) as long as he pledged obedience to the Crown and British government, which is the rub of colonialism. Except for 2 controlled visits to India, Maharaja Duleep Singh spent the rest of his life in exile. (His ... is a fascinating life and family. His daughter Princess Sophia Duleep Singh was a prominent Indian British suffragette who was instrumental in helping women win the right to vote in Great Britain. It's admirable how the family balanced retaining their Indian heritage with assimilating into high English society. The Maharaja longed to return to his throne and wrestled with a measure of regret in adulthood; still, he remained respectful and a close friend of Queen Victoria.)

Replica of Kohinoor Diamond before recut
The earliest recorded weight of the Koh-i-Noor Diamond is 186 carats. Cut in the style of Mughal-era diamonds, it resembled the diamonds in the modern Iranian Crown Jewels. This was disappointing to Western eyes, so Prince Albert, husband of Queen Victoria, had it recut by a leading mineralogist, James Tennant, (removing some discovered internal flaws) into a more dazzling brilliant cut stone. The colorless D-grade diamond was cut into a cushion shape with excellent clarity. Unfortunately, it also reduced the size of the diamond from 186 carats (or 191 modern carats) down to 105.6 carats. Diamond experts all agree it enhanced the beauty of the diamond and yet, at the loss of its size and history.

Queen Victoria (and Prince Albert) were quite taken with and became lifelong friends of Maharaja Duleep Singh (and later on with his daughters). The British Queen showed Prince Duleep Singh his lost diamond. Reportedly the 16-year-old Maharaja grew silent with emotion while holding and twirling it for 1/4 hour in his hands ... surely recalling how it belonged to his family and was later seized from him at a tender age.

After Queen Victoria's death, the Koh-i-Noor was added to the Crown Jewels. It was mounted in the crown of Queen Alexandra, the wife of Edward VII to use during her coronation in 1902. Queen Mary (wife of George V) and Queen Elizabeth (wife of George VI) also used the Koh-i-Noor Diamond in their coronation crowns. Due to its enduring controversy, the diamond was removed from the crown for Queen Camilia's coronation in 2023. 

Ever since India gained its independence in 1947, there have been cries to return the Koh-i-Noor Diamond to India. Pakistan, Iran, and Afghanistan also claim ownership resulting from the diamond exchanging hands as a spoil of war by the victors of those countries over the years.

I realize how hair-splittingly difficult it is to determine what is the right thing to do after centuries of the Koh-i-Noor Diamond's complex history, however IMHO, India has the strongest argument for ownership. As a Westerner, I'm biased towards wanting the diamond to stay in the Tower of London, but there's no doubt the diamond was acquired as the spoil of war under the strongarm of colonialism coupled with the coercion of a powerless 11-year-old boy ruler to sign it away. In the 21st century, an 11-year-old cannot sign legally binding contracts or treaties.

I also recognize the fear of opening a Pandora's Box by returning the Koh-i-Noor Diamond to India. Granted, not everything in history can be made right because time makes it convoluted and impossible to correct every wrong. I think we must go on a case-by-case basis. Just because righting a wrong is challenging doesn't mean it should not be attempted.

Today there are no living Duleep Singh direct descendants, but India understandably still feels the sting of how the Koh-i-Noor Diamond was taken from its country. What a magnanimous diplomatic gesture it would be for the British royal family to return the diamond to India. They would likely not even miss it (having so many other jewels), and it would loudly honor India and the last owner of the diamond, Maharaja Sir Duleep Singh.  

Yikes, now Pakistan will dislike me for thinking that India has the strongest suit ... as it also has a logical claim. In modern times before 1947, there was only India, a colony of the Britain Empire. In 1947 the British colony became two independent states of India and Pakistan. Punjab was divided by religion, with the western portion becoming Pakistan, and the rest of Punjab becoming part of India So it's a judgment call. Perhaps all 3 countries with the royal family could sit down at the table to decide.

So what do you think? Great Britain has it, but who should own the Koh-i-Noor Diamond? A difficult and problematic question for sure!

*The timing of the East India Tea Company was not by chance. Whenever a boy ruler comes to the throne, other powers who want control of a country's land or treasures use the country's weakness as the time to strike. The head of the mighty East Indian Tea Company, Lord Dalhousie, said he targeted the Koh-i-noor Diamond with the aim of giving it to Queen Victoria to be added to the Crown Jewels as a symbol of conquest. An elaborate ceremony occurred for the 11-year-old Maharaja to hand over the jewel as a sign of his submission to the Crown. After recutting it, Queen Victoria wore the Koh-i-Noor Diamond as a brooch. It became part of the Crown Jewels soon after her son Edward VII became King.

Duleep Singh's mother was exiled to Napal and her son was adopted and raised by British diplomat John Spencer Login and his wife whom the boy grew close to, and it was a warm, trusting relationship. They took him on tours of Europe.

The Cullinan Diamond In The Crown Jewels

These 3 photos have a watermark, but the copyright is likely The Royal Collection. Who else has access to remove and hold the gems up? I volunteer next time.😁 

The Cullinan Diamond is the biggest gem-quality rough diamond ever found. Some geologists think the largest clear diamonds such as the Cullinan Diamond (and Hope Diamond) were formed 100s of miles deeper within the earth's mantle than 99% of other gem diamonds, which are also smaller. At one time, the land might also have been ocean floor. Uncut the 
Cullinan Diamond named after Thomas Cullinan, the owner of the Premier mine in South Africa, weighs 3,106 carats. Discovered in 1905, click here for a short history and here for the longer history and controversy of the diamond.

On THE SAVVY SHOPPER, I hope we can Ooh and Ahh over the majestic diamond plus appreciate how diamonds are nothing more than pure carbon rocks that billions of years and human hands turn into spectacular sparklers, i.e., the jewels they become. 

An expert diamond cutter studies a rough diamond's structure to determine how it should best be cut, usually aiming to keep as much of the gemstone as possible. After cutting, another expert polishes the diamond. 

The 3,106 carat Cullinan Diamond (↖that's it on the left) was cut into 105 stones by Joseph Asscher & Company in Amsterdam with the 9 biggest stones eventually ending up in the possession of the British Royal Family. Reportedly some were gifts and others bought.

Let's take a closer look at the 9 largest Cullinan Diamond stones now with the British monarchy, along with a helpful cheatsheet. I needed to refer back to it, focusing on the shapes, to get the remainder of the blog right!:👀 


The two biggest of the cut diamonds, Cullinan I and Cullinan II are sometimes called The Great Star of Africa and the Second Star of Africa, respectively ... as if keeping the cut diamonds straight isn't challenging enough!

Here's where those 9 large cut diamonds ended up ...

The Cullinan I, a pendeloque cut (which is an ornament-like round brilliant-cut pear) weighs 530.2 carats. It was placed on top of The Sovereign's Scepter in 1910 by Garrard & Company on the instruction of George V. On the right is how it looks standing alone. The Cullinan I is the largest colorless diamond in the world!
The Cullinan II is the 317.40 cushion cut center diamond in the Imperial State Crown, its placement also decided by George V. The Cullinan II is the 2nd largest colorless diamond in the world. 
The Cullinan III is a pear shaped 94.4 carat diamond. Along with the Cullinan  IV, a square cut 63.6 carat diamond it became a brooch often worn by Queen Elizabeth II.

The Cullinan V is considered a one-of-a-kind heart-shaped diamond, weighing 18.8 carats. It's set surrounded by even more diamonds and platinum into another brooch. Bling, bling, bling!🙂

The Cullinan VI is set into a 3rd brooch and to the right as it appears loose. It is an 11.5 carat marquise cut diamond. The Cullinan VIIIan emerald cut 6.8 carat diamond, is mounted on the top of the 3rd brooch.
The Cullinan VII, a smaller marquise cut 8.8 carat diamond, is dangling from the gorgeous emerald and diamond Delhi Durbar Necklace. Like many of the standout gemstones owned by the British royals, the Cullinan VII diamond is detectable.


The Cullinan IX is a pear shape diamond weighing 4.39 carats that is made into a ring.

So the cut Cullinan Diamond is numbered from biggest I to smallest IX stones in descending carat weight! The Cullinan Diamond stones I and II, which are part of the Crown Jewels, are on view at the Tower of London. Stones III - IX are not part of the Crown Jewels but are pieces in Charles III's personal jewelry.

Estimates for the value of the Cullinan suite of diamonds can be found, but none of the jewels are insured, and given their history, they are irreplaceable and priceless. When I was in London on a group tour in college, it was decided (not by me😁) that the lines were too long to see them.💂

Pretty Things Borrowed From The Internet

The following are pretty things I love but either can't afford; don't truly need; or for the sake of practicality won't buy them. I love big blingy diamonds but can't justify spending 36k plus on a single piece of jewelry, and I don't need more dresses or sandals. Still, I love them all:

The top👆image is a ring designed By Bonnie Jewelry, as a gift for her Hong Kong mother. It's a 3 1/2 carat center pear-shaped diamond with two 1/2 carat accent pear-shaped diamonds. They are D-grade diamonds. Unaffordable for us average Janes ... yet stunning! The ratio of the center pear shape is ideal. The cut for a pear doesn't get any better, and you will pay a mint for it if you aren't Bonnie's mother!
Unlike the diamond ring, Crown Princess Mary of Denmark's Moss And Spy Elodie dress is affordable for a gal with a job. The high-lacy neck and A-line skirt look lovely on her! I try not to buy what I don't need and really have no upcoming events to justify buying a new dress, plus I have suitable dresses if an occasion to wear one pops up.

At 1st glance, Birkenstock sandals are quite ugly, but everybody is wearing them on the streets of Manhattan and I'm told they are ultra comfortable. Yesterday a woman told me she haven't taken hers off since buying them. Averaging $145 for leather, they run up to $200. Can so many people be wrong? If you walk miles and miles on city pavement with arch support and stability, ugly becomes beautiful!

If I go far from home on foot, I don't wear sandals. All summer long I wear Old Navy $2 flip-flops, inside my apartment only. I already own a supportive pair of Merrell sandals that I wear if I travel by car, or walk short distances. Birkenstock sandals would be worth the cost if its contoured arch support lets you walk all over town with ease. For sure your feet are worth investing in to prevent foot problems! Certain colors go on sale for $72, but I'll pass until I need a new pair of sandals.


Nice things, eh? That pricey diamond ring makes me wish I were either Bonnie's mother or Kim Kardashian, otherwise, I'm happy to be me!

Let's Talk Diamonds, White Sapphires And Moissanites

Well Happy Birthday to me!💟🎉

I love gemstones, I think for the right reason. Not for their monetary value but for their connection to mother nature wherein they are created over billions of years ... combined with the modern artistry of wo/man whose skillful hands find, cut, and polish them to best show off their exquisite beauty.

For my birthday I got a set of the huge white gemstones I covet, namely a 4-carat brilliant-cut diamond eternity ring and matching 4-carat diamond stud earrings🤥 ... well to be truthful, not exactly diamond gemstones, but white sapphires. Remember my motto? First a dreamer, then a realistic!

Diamonds would cost a fortune, about $110,000+ for the diamond ring and around $33,000 for the stud earrings. Frankly, it's a foolish sum of money for a regular person to spend.

Although there are distinct differences in shine between diamonds and other white gemstones (a/k/a diamond alternatives) such as white sapphire and moissanite, the latter two are gorgeous substitutes for the wildly more expensive diamonds, so a gal won't have to hock her home nor do without her sparkle!

Photo: Italo Jewelry
White sapphire (corundum, a 9) and moissanite (silicon carbide, a 9.25) are right behind diamonds (carbon, a 10) on Moh's Scale of Mineral Hardness and therefore durable to set in rings. 
What follows are reasons you might consider white sapphire or moissanite over a diamond when buying a bigger stone ... and I'll briefly contrast their appearances.

The only reason to not buy a diamond is its greater expense IMHO. The big stones over 2 carats put too many zeros on a credit card which would send many of us into debt! In comparison to diamonds, white sapphire and moissanite gemstones are cheap, especially for a big size. All 3 white gemstones (diamonds, white sapphires, and moissanites) have a lovely sparkle, yet they sparkle differently.

In terms of brilliance (white sparkle) and fire (color sparkle), a diamond outshines white sapphires and has warmer flashes of light (a/k/a glitter; shine) than both white sapphires and moissanite which both have a cooler tone. Brilliant-cut diamonds have a rainbow of shine. White sapphires have a grey or silvery sparkle. Compared to diamonds, moissanite, too, has a cool, bluish brilliance and compared to white sapphires, more fire.

Don't buy a ring gemstone below an 8 in hardness if on a budget as you might have to replace it.

Moissanite's high refractive index (how light bends and passes through a stone) will make it sparkle across a room like no other gemstone, so if you're looking for a huge wow factor (like flashing people across a room😄), you can't go wrong with moissanite. 

Like diamonds, diamond alternatives can be either natural (white sapphire) or lab-grown (white sapphire and moissanite). There are enough white sapphires in nature to mine whereas moissanite is so rare that all moissanite in jewelry is lab-grown. Since white sapphires can be either natural or lab-grown, the seller is required to state which one you're buying. My birthday ring and stud earrings are lab-grown white sapphires, which doesn't bother me as I know what I'm getting for less money. Lab-grown gemstones are chemically and physically identical to the gemstones created in nature. They are less costly due to lower demand and production costs.

Each of the 3 gemstones has its own unique beauty.
With a good stone cut and jewelry design, you'll enjoy wearing the less in-demand stones without going broke, and only a jeweler will detect which of the 3 is on your finger, neck, or ears. I'm getting loads of compliments and having fun with my great big blingy stones that don't cost a fortune!

Critics (usually people who sell diamonds) will tell you that white sapphires and moissanites don't hold their value like diamonds, but if you haven't paid an arm and a leg for them what do you care? What's more, jewelry isn't an investment as you'll rarely make but often lose money when reselling pieces. Luxuries, including jewelry, are things of beauty, never investments!

Another negative you'll hear is diamond alternatives look fake. But they don't if you expand your idea of beauty. Remember: I love all gemstones! White sapphire and moissanite only look fake if buyers try to pass them off as diamonds. They don't look fake as white sapphires and moissanites!! Girrrlll, can't we love all 3 stones!?🙂
