What are the factors that affect the color of pearls ?
1. Trace elements in the culture water. The water environment is strictly required in the pearl culture process, and the trace elements in the water are important indicators that affect the color of pearls. The breeders can control it to a certain extent through chemical fertilizers and organic fertilizers. For example, if you want yellow pearls, use more fertilizers with high copper and zinc content in the culture waters.
2. Control of culture operation. I believe everyone has opened river clams. The inner color of the clam shell is different. According to the color distribution of the clam shell, if you are targeted when taking slices, you may produce different colors.
3. Cultivation method. The depth and sun exposure of the hanging pearl oysters will also cause different pearl colors.
4. Taking slices of different types of river clams is also an aspect. For example, the small slices prepared with the mantle of the dorsal horn toothless clams are implanted into the pearl oysters of the triangular fan clams, and the probability of light red pearls is greater.
5. Types of cultured mother-of-pearl. This needs to be said more. The river clams for freshwater cultured pearls mainly include triangular fan clams, pleated crown clams, toothless clams and beautiful clams. The pearls cultured in seawater include black lipped oysters, golden lipped oysters, white lipped oysters and Marsh oysters. Different types of pearl oysters will produce different colors of pearls.
