Pearl is a hard and rounded object produced by mollusks like pearl oysters. The unique luster of this gemstone depends on the reflection and refraction of light from the translucent layers. It is generally white but sometimes creamy or pinkish tinge. It may also be tinted with yellow, green, blue, brown, purple or black.
