Emerald evaluation is usually: color, transparency, cutting, and weight.
The color should be evenly distributed without impurities. It is good for pure and dark green (not blue, not yellow). Transparency, internal impurities, cracks, flaws, less scratches on the surface, and residuals. Cutting work must meet the proportion. Various processing surfaces must be regular and symmetrical. Weight, with carat, 1 carat is equal to 0.2 grams. High -quality emeralds are the same as the value of the same weight.
The paulsive is expensive, so the imitation is constantly, and some use a gem similar to emeralds to replace them. The natural emerald has a hardness of 7.5-8, non-homogeneous body, with irregular cotton internally, containing three parcels or comma-shaped wraps. The color is calm, strong, and restrained, bright and clear, clear and clear. Below is a simple comparison with other green gems with emeralds:
green electrical stones: level 7 of the hardness, yellow and gray color, and there are no three -phase parcels inside.
Emerald: Hardness 6.5, oil to glass luster, translucent to opaque, fibrous intertwined structure, color mixing with the main body of gemstones, without three -phase parcels.
green glass: 5 levels of hardness, frivolous color, lack of emerald color characteristics, inside containing bubbles.
Profilmly, like other gems, and some also have defects. In order to increase its natural beauty and increase its value, emeralds for some emeralds with light, shallow, and cracks are used. Snowattic oil is immersed to make it perfect. In addition, there are emeralds that fill the defects with resin transparent glue, but under the magnifying glass, you can find that the thickness of the filler will remain bubbles and the luster is dark. In order to deepen the color of the emeralds, it is immersed in chemical paint, but under the high magnification, you can also see the internal green internal green infected with the grammed spider web -like distribution.
This above is just the basic method of identifying the authenticity of emeralds. To truly master the authenticity, naturally it needs more practice and look at the real objects.
It is impossible to identify the emerald ring with the naked eye. Jewelry identification is a combination of theory and practice. It has very high comprehensiveness and needs to be used by various instruments to have strict requirements for the environment. Emerald is identified. The appraisal of emerald rings is generally tested from the basic nature of gemstones of ancestors and grandmother. It mainly detects the refractive index, weight, absorption spectrum, etc. to determine the genus of emeralds. These must be used. If you can get a certain result, you need to be further tested. The as ordinary consumers do not need to worry too much when purchasing emerald rings. You can understand the detailed parameters of the emerald rings according to the jewelry appraisal testing certificate of the emerald ring, including the weight, size, color level, color level, color level, color level, color level, There are no optimization treatment, oil content, origin, etc., but you still need to pay attention to it, don't rely too much on the certificate. I have already bought it, but I can also go to the nearest quality inspection station for re -inspection.
