1, see the specification.
The bigger and rarer the pearl, the higher its value. The more difficult it is to raise a pearl per 1mm, the longer the growth period, the less the yield by half, so the value of a pearl with a difference of 1mm has at least doubled.
Step 2 look at the circle
As the saying goes, the rounder the pearl, the rarer it is, and the value from high to low. The value of round or nearly round pearls is several times higher than that of oval pearls.
3. Look at the luster
Gloss is the soul of pearls and one of the most important factors to judge the value of pearls. Pearls without light and shimmer lack aura and aura. Pearls with good luster can better reflect people. The higher the value, the less valuable the pearls are.
Step 4 look at the epidermis
Natural pearls more or less inevitably have natural defects, or "birthmarks", which is a symbol of nature. Almost all seemingly flawless pearls are one in a million, which is rare and of course more valuable. And a string of pearls made of dozens of pearls, even if it reaches the highest quality, can often find a little natural imprint, which is normal.
5. Color matching
Pearl earrings or pearl necklaces. In fact, it is not easy to find two or more pearls (strings) with the same quality at the same time, and it takes some time and technology, so a well-matched pearl usually has higher market value than a single pearl. A pair of matching pearl earrings is often worth twice as much as a pearl. With good earrings, the size and color are similar; The matched necklace and bracelet are similar in color, and the arrangement is not chaotic. Within a certain specification range, slightly larger pearls will be concentrated in the middle as far as possible, and the two ends will gradually become smaller to achieve the most beautiful wearing effect.
