When you buy Emerald Rings, Emerald Earrings and Emerald Pendants, there are several factors to consider - these are the 4 C's - colour, clarity, carat weight and cut.
Colour of Emerald
Emeralds occur in a variety of green colours. Some emeralds have yellowish to bluish overtones. The stone loses its colour when heated strongly.
The colour of an Emerald is its most important determiner of value. The best colour of an Emerald is "Emerald Green" or "grass" green. There is nothing else in the world that quite has this colour. It is not too yellow and not too blue; it is not pale or dark, but intense and bright. A quality Emerald looks like its glowing. Typically, the finest coloured Emeralds come from Columbia.
Again, the most universally accepted and most documented system of grading is the GIA system but there are also many commercial systems available.
Emerald Clarity
Unlike most gemstones, clarity is not large enough to determine the value of the emerald. It's definitely not as important as colour. This is because the inclusions are so common in natural emerald and it is thought not to interfere with its beauty.
Good transparency is still desirable, however, to the extent that the light is able to play in the stone, and it is transparent. Although no complete clarity is needed to make the Emerald exceptional value, completely opaque emerald is not worth much: in fact, even the best emerald, it is completely opaque, can no longer be valuable. Clarity is the second most important of the 4 C when you consider quality.
The clarity of Emerald, as with all other gemstones, is officially classified as ranging from the best VVS (very, very, slightly included), to VS (very, slightly included), SI-S2 (slightly included), and down to I1,I2,13 (included).
Weight of Emerald
Very large Emeralds (over 10 cts) of good qualities are extremely rare. Most of them are in museums, crown jewels or the jewellery boxes of the elite. Emeralds over 3 cts are even rare, available to average people for thousands of pounds. An Emerald of good quality of any size is valuable, though the price will go down significantly when the stone is less than 1/2 carat.
Emerald Cut
A good cut means Emerald to sparkle and shine in its full capacity. Facets that are good is not so important in emerald, because as in the other gemstone, an emerald is worth more for the colour saturation, and it is often very included to still shine. The type of cut known as "emerald cut", which is now a popular cut also for diamonds and other precious stones, was actually originally created for the Emerald. This type of cutting was to emphasise the colour rather than the sparkle. However, it is increasingly important to know the difference between a good and bad cut, so that when you highlight a selection of Emerald, you can choose a well cut version. In assessing the emerald cut, you should look for:
"Fish Eye": If the bottom is not emerald cut at right angles, you will be able to see through Emerald rather than seeing the light reflected back to you.
Uneven facets: especially pronounced in emerald cuts, step cuts, baguette and princess cuts, which are common among Emeralds. These cuts have long straight facets instead of small triangles and diamonds. A poorly cut Emerald of this style will have one end smaller than the other instead of an even length.
Polish: Emeralds can be difficult to polish because of the natural structure of the crystal, so twirl the Emerald around, to see that each facet reflects light like a mirror with no rough or dull spots. Also, Emeralds are prone to internal cracks and fissures which can also appear on the surface. If you see any fine rough lines on the surface facets of the emeralds, it is a flaw in the cutting and you should avoid it as it can make your emerald vulnerable. In the wholesale gem trade, Emeralds are sold on a price per carat basis. Therefore, it would make sense that a 3 carat Emerald would cost more than a 1 carat Emerald, all else being equal. However, an additional factor is that it is rarer to find a 3 carat Emerald than a 1 carat Emerald. Therefore, not only is the total price higher, but the price per carat is also higher because of the added rarity factor.
Emerald Treatments
Almost every Emerald available on the market has been treated to improve its clarity. Because Emeralds are naturally full of cracks and fissures which make it more opaque and less attractive, it has become an industry standard to fill the cracks in Emerald, thereby improving its clarity. Traditional fillers are natural oils such as cedar oil. Over many decades, these oils may fade or "sweat." Although they are accepted and do not make an Emerald worth less, there is discussion regarding the permanence of the treatment. For a gemstone treatment to diminish not a gemstone's value, it must be "permanent". Other methods of filling cracks in Emerald are being explored such as waxes, resins and even glass. A substance is considered good for filling cracks in Emeralds when it reflects light in a way very similar to Emerald, thus making the fillings less noticeable.
While sealing cracks that are acceptable to improve clarity, it is sometimes also used to improve the colour. For example, green coloured oil is used. This is generally regarded as misleading and it is best not to buy these "coloured" emeralds. This can be detected under a magnification of 10x.
Please note: Emerald gems may lose the oils or fillers after a few years of wear. This is normal. The Emerald Gemstones in this condition become brittle and are more prone to cracking and breaking. Most local Jewellers are well informed to do the treatment required for Emeralds and you can avail of their services. This is a special care that should be done by a professional Jeweller and cannot be attempted at home.
Fake Emerald and Simulants
In recent years, synthetic emeralds have been busy in the market. They come with labels such as "created", "laboratory", "synthetic", "Chatham" (a major producer of synthetic emeralds). They are "real" Emeralds in the sense that they are the same mineral, the difference is that they were made in a laboratory rather than in the crust of the earth. Synthetic emeralds are generally much more transparent than natural emeralds, with less defects. It is also possible to find very attractive emerald-coloured plastic emeralds. Emeralds are created about 1/10 the price of natural variations of emeralds.
Wearing Your Emerald Jewellery
Do not do heavy works while wearing emerald jewellery. Protect the jewels from bumps and jolts. Also, do not put near sources of heat, because it can damage the oils and fillers in emeralds that have been treated. When you care for emerald gemstone jewellery you should take into account improvements/enhancements in the gem.
Caring for your jewellery Emerald
Emeralds should never be cleaned with very hot water, steam or any other solution that contains petroleum distillates or solvents.Those jewellery cleaning solutions are sold as such in the markets are not compatible with the oil treatment of emeralds. All jewellery containing emeralds should not be placed in ultrasonic cleaning equipment.
To clean an Emerald or Emerald Jewellery use a soft old toothbrush or a cloth piece dipped in luke warm water. Avoid soaking Emeralds in hot or warm or cold water. The water may seep into the treated fissures and dilute or dissolve the fillers. Exposing the Emeralds to heat may cause the fissures to expand and make your Emerald very fragile.
Take off Your Emerald Jewellery when not required and store in a safe place away from heat or dampness. The idea is to keep your Emeralds in good shape by avoiding the need for frequent cleaning of Emerald Jewellery.
My last words ..,
For instance, I have always strongly recommended that one should buy Emerald jewellery Emerald Rings carefully. Expect to pay more for larger gems and remember at the end of the day, "beauty is in the eye of the beholder". Then choose the stone you want, not what you are led to believe you want! Whatever the Emerald Jewellery size or shape you choose, be sure to wear it and enjoy it!
