Factors affecting the price of pearls.
Pearl types, Lustre, thickness of nacre, colour, shape, size, surface quality, treatment status. The most expensive type of pearl is the natural pearl, these were the only type available until about 1900, when Miki Moto started to produce cultured pearls. Cultured pearls are from farmed oysters, whereas natural pearls come from “wild” oysters. Also we have sea water pearls from the oceans and fresh water pearls from the rivers and streams. Seed pearls were very small pearls used extensively in Victorian jewellery. Artificial pearls are made from many materials often coloured glass.
