What are Pearls?

What are Pearls?

  • Built from hexagonal aragonite crystals of calcium carbonate. Pearls are formed in Clams, Oysters and Mussels, and are found in many parts of the world. They are usually white, sometimes with a creamy or pinkish tinge, but may be tinted with yellow, green, blue, brown, or black. Black pearls are often highly valued because of their rarity.

  • Pearls are either natural or cultured. Natural Pearls are harvested from the ‘wild’, while Cultured Pearls are cultivated in ‘Pearl farms’. Pearls are harvested from the sea bed (Saltwater Pearls) and Inland water bodies (Freshwater Pearls) - this was the primary source of all pearls till the fag end of the 1800's.
