Pearl color formation mechanism

The color of pearls is mainly determined by the following three factors: Type of pearl oyster: Different pearl oysters secrete different colors of nacre, which is the basis of pearl color. For example, the mother-of-pearl of South Sea golden pearls is the gold-lipped oyster, whose shell edge is golden, so it can produce golden pearls; the mother-of-pearl of Tahitian black pearls is the black-lipped oyster, whose shell is gray-black, and has a strong iridescence, so it can produce a lot of color variations; the mother-of-pearl of freshwater pearls is the triangle sail mussel, which can produce pink to purple carotenoids, thus making freshwater pearls colorful. Structure of nacre: Nacre is composed of multiple layers of tiny plate-like crystals, which have gaps between them. When light shines on the pearl, it will cause refraction, reflection and interference, resulting in different color effects. For example, the luster of pearls is caused by the reflection of nacre, the iridescence of pearls is caused by the interference of nacre, and the overtone of pearls is caused by the refraction of nacre. Environmental influence: The color of pearls is also affected by the environment, such as water temperature, water quality, light, food, etc. These factors will affect the growth and secretion of nacre by the pearl oyster, thus affecting the color of pearls. For example, in areas with higher water temperature, the metabolism of pearl oysters is faster, the nacre secreted is thinner, and the color of pearls is lighter; in areas with lower water temperature, the metabolism of pearl oysters is slower, the nacre secreted is thicker, and the color of pearls is darker.

Rare colors of pearls

There are many colors of pearls, but some colors are very rare, because they require specific pearl oysters, nacre structures and environmental conditions to form, and the output is very low, so they are regarded as precious pearls. Here are some rare colors of pearls:

Rich gold South Sea pearls South Sea pearls are sea water pearls produced in the Indian Ocean and the Pacific Ocean, mainly cultivated by gold-lipped oysters. The color of South Sea pearls is mainly white, silver, and light gold, but there are also a few rich gold pearls, which are one of the most precious colors of South Sea pearls. The hue of rich gold pearls is between yellow and orange, the saturation is very high, giving a luxurious and gorgeous feeling. The formation of rich gold pearls is due to the gold-lipped oyster’s shell edge has a layer of gold pigment, when these pigments are secreted into the pearl layer, it will form rich gold pearls. The output of rich gold pearls is very low, accounting for only about 1% of South Sea pearls, and most of the rich gold pearls have uneven colors, with deep and shallow changes, only a few of the rich gold pearls have uniform and pure colors, these pearls are more valuable. The identification method of rich gold pearls is to observe whether the color of pearls is natural, whether there are traces of artificial dyeing, such as color spots, color bands, etc. In addition, the luster of rich gold pearls also requires very high, to have a strong metallic luster, rather than dull oil luster.

Peacock color Tahitian pearls Tahitian pearls are sea water pearls produced in French Polynesia, mainly cultivated by black-lipped oysters. The color of Tahitian pearls is mainly black, but because the black-lipped oyster’s shell has a strong iridescence effect, the color of Tahitian pearls also has a lot of variations, such as purple, blue, green, silver, etc. Among them, the most popular is the peacock color Tahitian pearls, which is one of the most precious colors of Tahitian pearls. The hue of peacock pearls is between green and purple, the saturation is very high, giving a mysterious and noble feeling. The formation of peacock pearls is due to the black-lipped oyster’s shell has a thin film, when light shines on this film, it will produce different colors of interference light, forming iridescence effect. The output of peacock pearls is very low, accounting for only about 10% of Tahitian pearls, and requires the overtone of pearls to be uniform and strong, to be called peacock color. The identification method of peacock pearls is to observe whether the color of pearls is natural, whether there are traces of artificial dyeing, such as color spots, color bands, etc. In addition, the luster of peacock pearls also requires very high, to have a strong metallic luster, rather than dull oil luster.

The output of violet pearls is very low, accounting for only about 1% of Edison pearls, and requires the color of pearls to be pure and uniform, to be called violet. The identification method of violet pearls is to observe whether the color of pearls is natural, whether there are traces of artificial dyeing, such as color spots, color bands, etc. In addition, the luster of violet pearls also requires very high, to have a strong metallic luster, rather than dull oil luster.
