Farm
Nearly every pearl available anywhere in the world is farmed – cultured. Pearl farms tend to be stunningly beautiful places.

Faux Pearl
A false pearl bead manufactured by coating the inside of a hollow glass sphere or the outside of a solid glass or plastic sphere with a pearlescent coating which is sometimes pearl powder. Faux is a fancy word for fake. Also called shell pearls. They are of course perfectly round in shape, with great lustre and even colour. White shell pearls are very white, which is a give-away. All fake pearls feel smooth when rubbed on the teeth and the drill holes tend to be larger.
Fiji
There is a young but growing pearl industry in Fiji, and the pearls produced have a huge and stunning range of colours, mostly shifted away from typical Tahitian colours into the chocolates and earthy shades

Freshwater
A pearl grown in a freshwater river, lake or pond margaritifera mollusc. Often more irregular in shape and more varied in colour than salt water pearls freshwater molluscs are nucleated by creating a small incision in the fleshy mantle tissue and inserting a piece of mantle tissue from another mussel. This process may be completed 25 times on either side of the mantle, producing up to 50 pearls at a time. The molluscs are then returned to their freshwater environment where they are tended for 2-6 years. The resulting pearls are of solid nacre, but without a bead nucleus to guide the growth process, the pearls are rarely round.
