Pearls have been a source of fascination for centuries. They have been considered the most magical and feminine of all gems and are the only one created by a living organism. Pearls emanate a certain warmth and glow not found in other gems, due to their unique beginnings.

Pearls are found in pearl oysters. However, the origin of the pearl mystified humans for centuries. Many theories were put forward regarding the origin of pearls however, it wasn't until the turn of the twentieth century that the relationship between pearl oysters and parasites was discovered.

Pearls were created when a foreign body of some sort, such as a grain of sand or a parasite, found its way into a pearl oyster. The oyster reacted by coating the irritant with layer upon layer of the pearly substance known as 'nacre', that gives the pearl its unique appearance and iridescent beauty. This unique relationship gave birth to the natural pearl.
