Basic Checks, For Emeralds

Emeralds, Preliminary Check

An emerald has been known to man for many centuries, but was not always rightly identified. We give you a basic understanding for recognizing an emerald gem. Remember that emeralds are expensive gems, relying on just the basic criteria for identifying an emerald will not make you an expert in gem identification. It is really the duty of your gem or jewelry provider to guide you and ensure that you get a genuine emerald gem stone. Going a little further, it is also the responsibility of the provider to make sure that you get good value for the money you spend. Emeralds are available in a wide range of qualities, prices obviously vary according to quality.

How To Recognize An Emerald:

(a) Emerald is a green gem stone, it can sometimes show a bluish-green color hue. It is a variety of beryl, and when beryl takes on colors other than green, it is given a different name.

(b) All natural emeralds have inclusions and fissures. These are a natural characteristic of all emerald gemstones. The idea of an eye clean emerald gem stone is a myth. Good quality emeralds will have fewer inclusions and fissures as compared to medium and low grade emeralds. A good quality emerald could also have these fissures and inclusions away from the center and more towards the edge. This ofcourse depends on the angle and orientation of the rough emerald during the cutting process.

(c) In your study to identify an emerald, remember that an eye clean 'emerald' is most likely not an emerald gem stone at all. Impressive degrees of transparency can be noticed in high quality emeralds but, complete transparency is almost impossible to find. On the other hand it is possible for an emerald gem to be heavily included so much so that, the stone appears fully opaque.

(d) All emeralds are treated with natural oils to enhance their lustre. If you look at an emerald under a light source, you might be able to see 'patchy' portions. This is likely to be the natural oils in the stone, difference in refractive index of the oils and the emerald stone make those patchy portions visible.

(e) If you have some knowledge about using the Chelsea filter (gemological tool), observe the stone through the filter. Remember to have sufficient light hitting the stone during the observation. The green emerald will appear reddish with no trace of green through the Chelse filter.

The world of gemstones has some amazing man made fakes (imitations) and you need to be aware of this. A fake emerald gem could be a cheap piece of glass with an emerald color. It could also be a laboratory born gem that matches even the chemical composition (not just the color) of a natural emerald gemstone. Some of these fakes look so convincingly similar to natural emerald gems that, even regular gem buyers are confused  at the similarity. As a casual gem or jewelry buyer you might want to increase your knowledge about identifying an emerald but, when it comes to the actual purchase get an expert opinion that can be trusted.

Before we end this report on 'How To Recognize An Emerald', we would like to mention a few important things. Do not make a purchase decision for your emerald gem based on this brief report. The best way would be for you to find a gem and jewelry provider that you can trust. This might not seem very easy but, do some research and check online for gem and jewelry providers that provide abundant information through their website. A website with 'Click To Buy' icons all over the web page, is not the right source for high end gems and jewelry. It is also possible to request for a certified gem stone, with a certificate from a reputed gem testing laboratory. But once again, getting hold of a gem provider that you can trust is of utmost importance. You really do not want a fake certificate that has been printed to look like a credible document!
