The largest pearl-bearing oyster is the marine Pinctada maxima, which is roughly the size of a dinner plate. Not all individual oysters produce pearls.

Sea pearls farmed in the Philippines, typically produce golden pearls from the gold-lipped pearl oyster, which are currently experiencing a surge in popularity, resulting in increased market-demand, particularly in China.
