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.

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.
