The 3 Other Precious Gemstones In The Raw

Recently I wrote a blog about raw rubies before they are cut, polished and turned into jewelry. Today I’m posting images of the 3 other precious gemstones in the raw. When we visualize gemstones, mostly we see them as the sparklers they become after craftsmen and jewelers get their hands on them like the above Harry Winston diamond ring. Not how them start or grow in nature, but how they are finished, right? So let's look at a few images of gemstones as they are found in nature.

I. Diamonds are a single element. Formula: C. A diamond is an allotrope of the element carbon. Its structure is a rigid three-dimensional lattice where each carbon atom is bonded to four other carbon atoms in a tetrahedral arrangement. A diamond’s atoms are arranged in a crystal structure called a diamond cubic. The gemstone rates a 10 on Mohs Hardness Scale. BTW: Graphite, charcoal, and diamond are all allotropes of the element carbon.

II. Emeralds - are beryls, a mineral. Its formula, Be3Al2(SiO3)6, is colored green by trace amounts of chromium or sometimes vanadium. On Mohs Hardness Scale emeralds rate an 8. They were formed under the most violent of geologic conditions, which is why less than 1% of the world’s emeralds are eye clean. Unlike diamonds, inclusions and surface breaking fissures called  jardins are common and accepted in emerads.

III. Sapphires - are a variety of the mineral corundum. Its formula, α-Al2O3 consists of the elements aluminum oxide with trace amounts of iron, titanium, cobalt, lead, chromium, vanadium, magnesium, boron, and silicon. Sapphires register a 9 on Mohs Hardness scale. Blue is the most in demand color. When sapphires are yellow, orange, purple, pink, or green they are called fancy sapphires. When corundrms are red, they are rubies, not sapphires.

Gemstones take millions of years for the Earth to produce, or nowadays they can be grown in a lab, but it takes the artistry of human hands to turn these majestic crystals, beryls, and corundums into gorgeous pieces of jewelry. The next time you see a gemstone think of its journey and how many hands went into crafting it into a thing of beauty.

Buying An Emerald Ring The 4 Cs

Photo: TK, trying o locate source

Yesterday I popped into Tiffany & Co. to try on a few emerald rings for fun. I wanted to start with heirloom-quality stones to refresh my memory on their appearance and price, and oh boy, did Tiffany deliver! The emeralds are stunning, ultra expensive ... yet small for the price tag. The design and quality of stones are top-notch, making even a 1/4 carat of emerald surrounded by diamonds ring a showstopper. As much as I love looking and trying Tiffany rings on, the price points for tiny stones are beyond what I wish to pay ... and for the purpose of this post I'll assume you, too, want a bigger stone for less money. So today, let's go shopping for emerald rings!

Here are the 4 Cs that determine the value of an emerald, especially vital if you seek a larger stone:

1) Color - The color is the most important characteristic, but it is also the most subjective of the 4. Emeralds are a variety of beryl, a mineral whose green color comes from the impurities of chromium along with vanadium that are determined by where they are mined. Often customers prefer darker greens over lighter stones and a blue-green hue (cool) over yellow-green (warm). It doesn't make one better than the other, yet due to demand does influence price. Coveted Columbian emeralds tend to be bluish-green. (Click here for countries where emeralds are mined.)

When jewelers examine the color of emeralds they also

consider tone and saturation. The tone is the lightness and darkness of the emerald on a scale of 0 (white) to 10 (black). Fine emeralds fall between 2 and 8 on the scale. In this range, ultimately the beauty is in the eye of the beholder. As it turns out, customers gravitate to #5, #6 and #7 in color↑. I think of saturation (another name for tone) as the opaqueness or transparency of an emerald. I value opaqueness in leggings, but I desire as much transparency for the $buck$ as I can get in a colored gemstone as it shines more!

2) Cut (My 2nd important characteristic is usually listed as 3rd by experts. Trust me: I'm right, and they're wrong!🙂 Let me explain why.) The skill of the cutter determines the beauty and larger-look of the stone. A great cut maximizes the color, size, brilliance and takes note of the inclusions in the emerald. In fact, of the 4 precious gemstones, emeralds are per se a fractured stone. Its fractures/inclusions, called Jardins, are accepted as a natural characteristic and mark of its unique beauty. Emeralds without Jardins are 99.99 out 100 times fake.

3) Clarity - We discussed how an expert cut enhances the clarity of a gem. More light bounces off of it. Unlike diamonds, impurities and inclusions -- Jardins -- in emeralds are common and considered part of its natural beauty. Jewelers say: Each emerald has its own fingerprint of how it was formed by nature billions of years ago. With diamonds (carbon), you want them as clean as possible, yet nature rarely makes an emerald (beryl) clean (without Jardins). In French Jardin means "garden." And if an emerald doesn't have them, have it tested. You're either set for life ... or own a fake!

4) Size - As with all gemstones, bigger stones are rarer so prices rise exponentially per carat. Each additional carat of the same quality of emerald more than doubles and triples in price. Rats!!!

Just like emeralds, shoppers are all unique, so different strokes for different folks. Personally, I would forget about buying heirloom-quality emeralds. You'll have to pay $8,000+ for 1/4 carat stone surrounded by 1/2 carat of tiny diamonds. Paris Hilton, you can ignore my advice.

 

😍Macy's comes through again! What an Effy beauty on a budget!!

Everybody else, if you consider commercial-grade stones, a 2-carat emerald is not cheap either, yet reasonable and doable as a luxury splurge for a working person on a budget (especially during a Macy's jewelry sale)! Moreover, a stone over 2 1/2 carats gets very expensive, what you would pay for a car, or the downpayment of a house.

Every splurge should be worth the money spent! When the verdict is, "I LOVE it," without going broke, it is.💚

Walking Up - Down Madison Avenue

Can't go wrong with this designer

Walking up or down Madison Avenue to see the latest fashions is one of the great pleasures of being in Manhattan. The shop widows can be summed up in one word ... magnificent. LA's Rodeo Drive is shockingly pint-sized compared to the 6 miles of Madison Avenue. On the Upper East Side stretch (comprising 1.5 miles between East 86th Street to East 57th Street, there are about 400 luxury and flagship stores, selling apparel, shoes, high end accessories (like purses, belts, hair ribbons, etc.) and fine jewelry.

All that glitters is gold!

These twinkling diamonds, sapphires, rubies and emeralds at Travelers Jewelers on Madison (at East 77th Street) are huge and real gold and gems! I swear, they blink at me every time I walk by!

Georgio Armani (at East 66th Street) has shimmering windows too ... presently featuring evening gowns. Despite the glare from the street lights and traffic, I'm posting a few. There are many more to see!

Wouldn't the elegant designer dresses look lovely with some jewels? Feel free to select your favorite necklace, bracelet and/or ring.

Next razzle dazzle up the avenue stopping at Giuseppe Zanotti (on East 68th Street) for a pair of embellished fancy shoes.

This 12 carat sapphire ring with 14 solitaire diamonds in white gold is my favorite. A kind salesman let me slip it on my finger, and it's a perfect fit! Each time I pass Travers, I look for it in the window. But alas ... after months and months, somebody with deep pockets walked into the jewelry store and bought my ring! {Are you reading this? That's right, MY ring, sister! I know your ring size!!}😁 Fortunately, I have this photo to show you. What a beauty ... I will miss it!😍

On Madison Avenue there are ever changing pretties to see, and the exercise and eye candy are free!
