About Pearls


Pearls are gems that form inside a living mollusc. They exist in a wide variety of sizes, colours, and shapes influenced by a variety of factors, such as mollusc species, environmental conditions and human interference.

Natural pearls form when the mantle of a mollusc is irritated by a foreign “intruder.” The mollusc secretes calcium carbonate, often in the form of nacre, to protect itself from the irritant. As the mollusc deposits more and more layers, a pearl forms. Most natural pearls are small and irregular in shape. Large pearls with round or drop shapes are incredibly rare and valuable.

Cultured pearls form through human intervention when a nucleus is planted into the mollusc to spur pearl growth. The nucleus is often a round shell bead, which helps determine the size and shape of the pearl that forms. The most common cultured nacreous pearls are South Sea, Tahitian, akoya and freshwater.
