When I first started in the jewelry business, we carried emeralds – or something that was supposed to look like an emerald but really looked more like square boogers. Many were off color – almost grey-green, and most were very small set in the typical ring, earring and necklace mountings. Wearing boogers is not cool. As you will read below, color is the main thing that makes an emerald valuable.
Emeralds have been prized for thousands of years for their lush green hues and rare beauty. Throughout the ancient world, emeralds symbolized eternal hope, rebirth and the arrival of spring - and some cultures believed the gem rewarded its owners with love, intelligence, eloquence and great wealth. Colombia continues to be at the top of the list of the countries in which fine emeralds are found. Colombian emeralds differ from emeralds found in other deposits because they have an especially fine, clear emerald green hue. This beautiful color is so valued in the international emerald trade that even obvious inclusions are regarded as acceptable.
STATISTICS AND CARE
Emeralds rate 7.5-8 out of 10 on the Mohs hardness scale but they can be fragile due to the inclusions which are found naturally in the stones. It's actually OK to see those little marks and lines throughout your stone. Emeralds require more special care than most stones (that alone should tell you something....anything that requires more care than your hair requires further thought). They should never be submerged in hot water or placed near heat sources so wearing them can give you a good reason not to have to cook. Never put your emerald in an ultra-sonic machine to clean it as the intense vibrations of the machine can pulverize a stone and break it apart. This actually happened to one of my colleagues. They wound up straining the emerald dust through paper towels while schvitzing in the back room and had to order the customer a new ring...believe me, you only learn that lesson once in your life. Be sure take off your emerald jewelry before you do dishes (another reason to wear them – you don’t have to do housework either) as cleaning products can remove the oils used to protect and seal a stone after it’s been cut. You can use a very soft toothbrush along with water to clean a stone then wipe it dry with a soft cloth. Every 2-5 years emeralds should be re-oiled by a professional. Be sure the jeweler you use is familiar with handling these special stones.
COLOR
As I said before, color is the most important aspect when considering emeralds. Generally speaking the darker the color the more valuable the emerald. However, just because an emerald is dark green does not make it valuable. A fine emerald will have a dark blue green color while at the same time be translucent and brilliant. Fine inclusions do not diminish its value. On the contrary, even with inclusions, an emerald in a deep, lively green still has a much higher value than an almost flawless emerald whose color is paler. There are many dark opaque stones that are very cheap (unfortunately, this is what you see most often in department stores). Obtaining good color in emeralds at an affordable price was the reason my store stopped carrying a large assortment of these stones and why I never purchased one of my own. Even with my store discount, a really good emerald was still so expensive, that along with the fragility of the stone, I was concerned I wouldn't be comfortable wearing it all the time, therefore, it wouldn't pass my “Times Per Wear” test. TPW is my theory for buying something expensive and it’s a good rule to employ. If you are not putting your new thing on while in the car in the parking lot, wearing those new shoes right out of the store, or wearing your new thing so much your friends are saying...."uh...don't you have anything else to put on," you must rethink your purchase. You have to feel wanton lust for it, immediately rip off those tags, put it on and then proceed to wear it until you are bored with it. People who have new things in their closets with tags that have not yet been test driven saving it “for something good” are totally breaking the TPW rule.
CLARITY
We've established that emeralds tend to have numerous inclusions. Unlike diamonds, where a 10x loupe is used to determine quality, emeralds are graded by eye. If an emerald has no visible inclusions to the eye it is considered flawless. Stones that lack inclusions are extremely rare and therefore almost all emeralds are treated, or "oiled", to enhance the apparent clarity. Pure green emeralds with no inclusions are one of the most expensive stones you can buy. Although my normal everyday assortment of emeralds was not of top quality, I did have access to a few wonderful vendors who carried top notch beautiful stones. You might not think customers would buy an expensive emerald from a large retailer, but we did sell a magnificent emerald ring to one of our best customers by bringing stones in for her to review and then having her selection set by my jeweler. We sold the four carat emerald cut emerald with trillion cut diamonds on either side for approximately $25,000. This client trusted us so much she didn’t mind paying the premium that can come with buying retail. This is why my phone number was on speed dial with many of my clients - they trusted me.
CUT
The cut is usually the most boring part of the four C's and many people don't understand how important it really is. The faceting, shape, width and depth of the emerald make up the cut. The ideal cut emerald will be symmetrical and have uniform facets that provide for maximum color and brilliance. Round emeralds are least common because you must waste more material to cut a round but you can find them, along with oval cuts, used as cabochon stones (rounded and smooth rather than faceted) as a center or accent stone. A rectangular step cut known as the "emerald" cut is generally thought to produce the best end result for emeralds and, in my opinion, along with a square cut, is really the only cut for an emerald stone.
CARAT WEIGHT
Although size really does matter, the actual carat weight of an emerald is not as important as the color or clarity when determining the value of a stone. An eight carat significantly included emerald of dark color without translucency would not be as valuable as a four-carat stone of impeccable color, translucency, and a few inclusions. Thus, the color, clarity, and cut should be taken into consideration before carat weight. I've decided, after looking at the following images of amazing emeralds, that if I can't wear it on my head or pin it to my boobs, I'll probably never own one.
WOW EMERALDS WORTH LUSTING OVER.....
Angelina Jolie's 115 carat Lorraine Schwartz Colombian emerald earrings and 65 carat emerald ring worn to the 2009 Oscar’s. Not sure if Jolie owns these gems or borrowed them. Lorraine Schwartz, who makes some of the most amazing pieces out there, does not pay celebrities to wear her jewelry as some jewelers do as a way to advertise. The earrings alone are valued at $2.5 million.
Of course only Angelina Jolie would wear the most amazing oval cut emeralds that completely debunk the information I provided on the cuts of stones but I'm using her jewelry anyway.

Is it wrong to wear an emerald as large as your kneecap when going food shopping?
The center of this brooch is a hexagonal-cut Colombian emerald of 60-70 carats, secured within an openwork two-tiered rose-cut diamonds border, surrounded by a row of old mine-cut diamonds, mounted in silver-topped gold, from the mid 18th century. The brooch stem may be detached and the brooch may be worn as a pendant with an additional pendant hoop.
An important imperial jewel, the Catherine the Great Emerald and Diamond Brooch evokes the bygone days of Russian majesty. It is a testament to an empire and a glittering memento which adorned princesses, grand duchesses and empresses alike, and is now being offered at auction for the first time in 40 years. With such a history, the possession of a jewel of this quality and rarity would certainly be the center of any modern collection.
It was acquired for Catherine II of Russia after she ascended to the throne in 1762 and it became known as one of the most outstanding jewels in her vast collection. To historians she is Catherine the Great. To Russian nobles and commoners of her time she was the "beloved mother" of her people. With not a single drop of Russian blood in her veins, for her contemporaries and for successive generations, she was to become the very embodiment of Russia, ruling a mighty empire for thirty-four years. "Russia above all" was her credo. Christie's Features Archive, 30 March 2010.
