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, mainly because emeralds themselves have more inclusions (natural fingerprints) than other gemstones, so Many scholars call it the "garden" of emerald. Therefore, in the industry, the clarity of emerald is very important. The impact of price is not as big as the impact of color. Generally speaking, some emeralds on the market will have more or less flaws. If inclusions or flaws are not visible to the naked eye, there are three situations. One situation is There are sky-high price pure natural emeralds, one is emeralds that have undergone some kind of artificial treatment, and the last one is probably fake.
