Is there such a thing as a blueberry pearl?
Oh, I see. Do you know what causes pearls to have different colors?
Yes, the color of a pearl is determined by the type of shellfish that produces it and the environment it grows in. For example, pearls produced by oysters that grow in warmer waters tend to have a golden color, while those produced by oysters in cooler waters tend to be white or silver.
