Mixed-color peacock pearls are artificial pearls made by modern technology. They are usually based on clam shells and then coated with colored paint or metal layers. Compared with natural pearls, the value of mixed-color peacock pearls is lower. Natural pearls are formed by shellfish in the natural environment, while mixed-color peacock pearls are artificially made.

Peacock pearls with mixed colors are usually made into jewelry, such as necklaces, earrings and bracelets. Although they can be used to enhance decoration and fashion sense, their market value is relatively low, because they do not have the uniqueness and rarity of natural pearls.

To sum up, the market value of mixed-color peacock pearls is relatively low. If you are really interested in pearls, I suggest you look for natural pearls, which are rarer and more collectible.
