Color: Pearls have an iridescent "pearly" luster and are noted for their wide range of color; they can be found in white, silvery white, pink, salmon, red, copper, bronze, brown, lavender, purple, green, blue, cream, and yellow.
Gem Info: Pearls are known as one of the four organic gems along with Coral, ivory and amber because they are produced by a biological process. Freshwater pearls form in mussels and clams that live in lakes or rivers, and are often found in irregular shapes.
Healing Properties: Pearls are said to promote wisdom and contentment well into old age. They are believed to alleviate or cure chronic headaches by wearing the pearls directly on the skin, and they are thought to reduce allergies.
