Today I’d like to feature red and pink diamonds. Natural red and pink diamonds are the rarest diamonds* on earth. Natural pink diamonds make up less than 0.01-0.1% of all gem-quality diamonds mined, while natural red diamonds make up less than 0.00001% of the diamonds mined. Many of them were found in the now closed Argyle mine in North-Eastern Australia.
Fancy colored gemstones usually form when impurities such as boron or nitrogen enter their atomic structure. This is not the case for pink or red diamonds. Their colors are caused by a distortion in the diamond's crystal lattice produced by intense heat and pressure from all directions after the stone's formation in the earth, an ultra rare occurrence! A special configuration of molecules lets us see the stone as pink or red as light passes through it.
Red diamonds are often less than a carat in weight. 👈The Moussaieff Red Diamond, a trilliant-cut, internally flawless 5.11-carat red diamond, is the largest known red diamond in the world. Discovered in the 1990s in Brazil’s Minas Gerais region, it weighed 13.90 carats in its rough, uncut form. Auctioned for $8 million in 2001, experts think it would fetch $20 million today due to the double rarity of its color and size.
The Argyle Phoenex👉 at 1.56 carats is the largest brilliant round cut fancy red diamond in the world. The ultra-rare pure red gemstone came from the now-depleted and closed Argyle mine. It sold for a record breaking $4.2 million at a Phillips auction in Geneva in 2024. Small, yet intense and stunning!
Frankly, unlike red diamonds, I’ve never been enamoured by pink diamonds until the 👆Eternal Pink diamond came along. At 10.57 carats, it’s not the biggest pink diamond in the world, but IMHO it’s the most gorgeous, plus I love the diamond's exquisite ring setting. The Eternal Pink diamond is a cushion cut internally flawless Fancy Vivid Purplish Pink color reduced from a 23.78-carat rough stone found in Botswana. In 2023, it was sold at Sotheby's for $34.8 million.
Many of the world’s other big pink diamonds are less saturated, so a paler pink and so large, they don’t look as lovely on a finger, which is not to say you wouldn’t ogle them upon sight.
The CTF Pink Star👉, mined in Africa by DeBeers,is not only the biggest and most expensive pink diamond ever sold, but it is the most pricey gemstone ever auctioned. Costing $71.2 million in 2017, the 59.60-carat oval-mixed cut stone is internally flawless and graded by the GIA as a Fancy Vivid Pink Diamond.
Golly-gee, is it an enormous diamond to wear as a ring, but I’m sure I could get used to all the carat weight, if I had to wear it.:)
👈The Desert Rose is the largest and most famous pear-shaped diamond in the world. A 31.68 carat Fancy Vivid Orangy Pink diamond, with VVS1 clarity, it sold at Sotheby’s for $8.8 million in 2025.
The Fortune Pink,👇 a mere 18.18 carat diamond graded Fancy Vivid Pink by GIA with VVS2 clarity,wasthe previous largest pear-shaped Fancy Vivid Pink diamond. Christie’s auctioned it for $28.8 million, and I’m going to show you its luminous beauty below. The new owner can wear it mounted as either a ring or a necklace.
Pink and especially red diamonds start as the rarest gemstones on Earth, and as their natural supply dwindles, their value will keep rising! But more than their monetary value, they are a true, rare, natural phenomenon. Reminders of Mother Nature’s powerful forces and lustrious beauty.
*Red gemstones are the rarest type of gemstone. Rubies are also rare.
Taaffeite is one of the rarest gemstones in the world. It was first discovered as an already cut, polished, and misidentified "spinel" in a Dublin, Ireland jewelry shop by gemologist, Richard Taaffe who bought a cluster of gems in October 1945.
Taaffe noticed some inconsistencies in his "spinel" and sent a sample of the stone off to a London lab which in 1951 verified that its main components were beryllium, magnesium, and aluminum, making the hexagon crystal a newly found mineral later named taaffeite (BeMg3Al18O16).
Unlike spinel, which is only singly refractive (like diamonds and garnets), Taaffeite is doubly refractive (it blends and reflects light in all directions).Taaffeite is a transparent gemstone with a vitreous shine (like glass in appearance or physical properties).
This beryl forms in carbonate rocks in Sri Lanka and Southern Tanzania (alongside the gemstones fluorite, mica, spinel, and tourmaline). Some poor-quality taaffeite has also been discovered in China.
Because of its rarity, taaffeite is only used as a gemstone. Registering an 8 - 8.5 on Moh's Scale of Hardness, the jewel comes in colorless, violet red, pink violet, red, light green, and mauve. Taaffeite costs an average of $1,500 - $2,500 per carat, although top-grade taaffeite can fetch $35,000 per carat. The best quality taaffeite gets bought quickly. Pink is the rarest and most expensive color.
This beryllium-magnesium-aluminum-oxide mineral is clean of inclusions, and the red is gorgeous.Imagine ... a jewelry lover wearing it would bling all over the place!
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.
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 hisdaughters). 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 IndiaSo 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.
Today I'm showing my jewelry-loving readers ornate, historical eye candy. My original idea was to feature in detail 10 famous Crowns of western countries, but guess what? In my research, I discovered Matt Baker of UsefulCharts has already compiled them and as usual, his work is excellent. Well, thundering typhoons ... Matt Baker, not only did you beat me by a year, you took away the illusion that my brilliant idea is unique ... the nerve!🙂
So instead, I'll play a game of picking my favorite European royal crowns leaning towards coronation crowns (since many European royal houses have more crowns than we can count). Thanks to Matt Baker's thoroughness, you can watch his video here for the history and details of my 6 favs (plus a few more on his list of 10 famous crowns). As it turns out he did the work for me on this topic!
So here are My 6 Favorite Royal Crowns - I've included not 1, but 2 from the United Kingdom because Queen Elizabeth II uses two. Both have crowned English and British monarchs, and I don't want to break them up. Drum roll, please🥁... here we go:
1) The Crown of Rudolf II, later the Imperial Crown of Austria - Made in 1602 to crown Holy Roman Emperor Rudolf II, it became the official crown of the newly constituted Austrian Empire in 1804 and today is preserved in the Austrian Imperial Treasury. The crown is pure gold, partially enameled, and scattered with diamonds, sapphires, rubies, emeralds, and pearls. Wow, the Ceylon blue sapphire at the top is stunning!
2) Imperial Crown of the Holy Roman Empire - Here is a side view in addition to the front view at the top👆 of the blog. Thought to be made in 962 AD in Western Germany for the coronation of Holy Roman Emperor Otto I, the crown has 8 hinged 22-carat gold plates of images joined together forming an octagon shape. It has 144 unfaceted stones including sapphires, emeralds, and amethysts, plus pearls. To think that it sat on the head of Charles V on February 24, 1530, along with prior Holy Roman Emperors and we still have it! Nowadays it is kept in the Imperial Treasury in Vienna, Austria.
The Imperial State Crown
3) (a) The Imperial State Crown [of the United Kingdom] - Shown is both the front and back view of the crown, it was selected by Queen Victoria and Edward VII for each of their coronations. Queen Elizabeth II uses the Imperial State Crown to open Parliament. It has 2,901 precious stones, including the familiar Cullinan II diamond, St. Edward's Sapphire, the Stuart Sapphire, and the Black Prince's Ruby (which is really a red spinel).💂
St Edward's Crown
(b) St. Edward's Crown (also part of the UK's crown jewels) - The original crown was made in the 11th century, named after the last Anglo-Saxon English King, Edward the Confessor, and remade for Charles II for his 1661 coronation after the Restoration of the English monarchy in 1660. It's considered the traditional coronation crown of English/British monarchs. George V, George VI, and Elizabeth II used it for their coronations. The heavier of the 2 crowns, it weighs 4.9 pounds and is set with 444 precious and semi-precious gemstones. Oh, a gal who's also a monarch cannot have too many stately crowns, can she?
4) Imperial Crown of Russia - First worn for the coronation of Catherine the Great in 1762 and last worn by Nicholas II in 1896. The crown also sat prominently on a chair when Nicholas opened the Russian Duma in 1906. Thankfully, it survived the Russian Revolution of 1917 and is currently on display at the Kremlin Armory Museum in Moscow, all 2,858 carats (or 4,936 single) diamonds, 75 Indian matte pearls and a 398.72-carat red spinel (once mistaken for a ruby).
5) Crown of Saint Wenceslas - Made in 1347 to use for the coronations of the Kings of Bohemia (modern-day Czechoslavia). Ferdinand V was the last to be crowned wearing it in 1836. The crown is reportedly 22-carat gold. The stones decorating it -- consisting of 19 sapphires, 44 spinels, 30 emeralds, and 1 red elbaite -- are polished and not cut in facets so the crown is old-world vintage, colorful and charming! But a terrible "legend" follows it: "Any usurper who places the crown on his head is doomed to die a violent death within a year." (source: Wikipedia + others) Since I'm a gal just having fun as an admirer, not a usurper, would I be cursed placing it on my head?
I cannot identify all of the above👆 coronation crowns but am happy they survived the centuries of history, and I'd love to visit each and every one of them. If pressured, I could be persuaded to try them on. (No, no I shouldn't ... I couldn't, I shouldn't, please no, no, no ... oh if you insist, alright.👸🏻) How about you? Feel free to name them or reveal your favorites in the comments.
