The price of emeralds is not low, and they are loved by both sexes. There are many counterfeit products on the market, and there are many counterfeiting methods. Like the sandwich sandwich method, there is only a thin layer of emeralds in the sandwich. Some people also use the oil immersion method to make the emeralds seem to contain less. It is also more beautiful and more transparent, but over time, when the oil dries, cracks appear on the surface of the gem. En outre, some merchants use dyeing methods to inject wind oil or artificial chromium into the cracks of the gems to give the gems a beautiful color.

To crack the sandwich method, you can observe from the side of the gem. It is not difficult to see the layer by layer. You can also illuminate the side of the gem with a strong light, and you will see the presence of adhesive. If you want to crack the oil immersion method, you also use strong light. If the emeralds appear rainbow-like colors under the strong light, then 90% of them are immersed in oil. Wish you didn’t buy green oil emeralds? Then observe with a ten times magnifying glass, the emerald after dyeing with green oil will fade and cracks after a period of time (six months to a year).

The grade of emeralds can be evaluated from color, clarté, contrast of light and dark, and hue. The green of emeralds of general grade must be at least medium and light to be called emeralds. But if the color is too strong, it is not a good product. The closer to the green of the traffic light, the higher the grade. Almost all emeralds have inclusions. In terms of clarity, grandmothers with a boat-like level have more inclusions, and emeralds with higher levels have fewer inclusions. But basically natural emeralds must have natural impurities, so in gemology, emeralds have the reputation of “flaw garden”.

Judging from the contrast of light and dark conditions, since emeralds are not pure green, they may be green with yellow, or green with blue. If you can see yellow or blue under normal light, it means that the contrast of this emerald is obvious, and the level will be raised.

Emeralds are royal jewels, costing more than 1,000 yuan per carat. At international auctions, top-quality emeralds can reach tens of thousands of yuan per carat. Since emeralds rarely exceed 3 carats, the larger and more beautiful emeralds, the higher the price. The author once saw a 7-carat top emerald with a price of more than 800,000 yuan.

À présent, there are only two emerald producing areas in the world. Colombian emeralds are “green with blue” and Brazilian emeralds are “green with yellow”. Parmi eux, emeralds with green and blue are more expensive. Lors de l'achat, you might as well ask the salesperson: “Which origin of emerald is this?” Then observe the color according to the origin, not only can be used as a standard for purchase, but also one of the methods of anti-counterfeiting!
