Cherished as symbols of purity and perfection, elegance and affluence, pearls are unusual gems, created inside living animals called mollusks. Occurring naturally in a wide range of sizes, shapes and colors, pearls have long captured the attention of scientists as well as socialites. 

Any mollusk that produces a shell can produce a pearl. Nevertheless, naturally occurring pearls are rare, found in perhaps one of every 10,000 animals.

Indeed, more pearls are produced now than at any time in human history.
