[May Birthstone—Emerald (Emerald) Selection Knowledge and Gemstone Rating]


Whether emeralds (emeralds) are good or beautiful, you can actually first look at whether you like the color, and then whether the style suits your eyes. If you want to know more about the rating of emeralds, you can look at its color, clarity, weight, Start with several aspects such as processing and origin.

color:

The color of emerald is an important factor that affects its price. It can generally be simply divided into light green, bright green (the highest grade), emerald green (the most popular) and dark green . Some professional identification agencies (such as GemResearch Swisslab AG ) " Muzo Green " or translated as "Muzo Green" will be set as the highest level of its color. Muzo Green refers to the level of color saturation and brightness reaching " Vivid Green" , that is, its green color is pure and rich . In addition, Muzo green must also meet many conditions such as being produced in Colombia, specified cutting quality, and high standard clarity before it can be rated as " Muzo green " . Because the conditions for " Muzzo Green " are too harsh , some organizations have proposed the color standard of " Verdant Green" , which means that regardless of origin, as long as high-quality emeralds are bright green, they are called " Verdant Green". green " .

Based on years of market experience, WILLS has concluded that the color with the highest rating on the market may not be what most people like.

Cleaness:

Although clarity is one of the indicators for evaluating emeralds, the most standard tool for judging the cleanliness of emeralds is our naked eyes, which is different from diamonds. For example, the price of a flawless emerald under a ten-fold magnifying glass Compared with emeralds that are flawless to the naked eye, the difference is basically not big. This is mainly because emeralds themselves have more inclusions (natural fingerprints) than other gemstones. Therefore, many scholars call it the " garden " of emeralds. , so within the industry, clarity has less of an impact on the price of emeralds than color. Generally speaking, some emeralds on the market will have more or less flaws. If inclusions or flaws cannot be seen with the naked eye, there are three situations. One is a sky-high price pure natural emerald, and the other is a emerald that has been processed through a certain process. For artificially processed emeralds, the last case may be a fish out of sight.

Naturally produced emerald crystals are not large, generally rarely exceeding 8 carats, and high-quality emeralds above 10 ct are rare treasures. Generally, the weight of emerald-cut emeralds can be initially estimated by counting outward from the table surface of the gemstone. Usually 2-3 layers are in the range of 1-5 carats; 3-4 layers are between 5-10 carats .

deal with:

The optimization treatment methods for emerald mainly include: dyeing, resin injection, colorless oil injection, film coating, etc. However, dyeing, lamination, resin injection, etc. are treatments and must be clearly marked on the product label when selling. Oil injection is optimization and is sold as natural. Due to the low natural clarity of emeralds, most emeralds have been soaked in oil during the mining and transportation process, which is recognized by international standards. The main purpose of soaking in oil is to reduce the visibility of internal cracks, improve the clarity and protect the emerald itself.
