Cultured pearls are created in nature with human intervention. Cultured pearl
exists in two categories - freshwater cultured pearl and saltwater cultured
pearl (akoya, Tahitian and South Sea). But "Cultured pearls" is still
commonly used today to refer to akoya pearl. It is important to know that a seller can
describe freshwater pearl as cultured pearl which is not wrong. Just
make sure whether it is freshwater pearl or akoya pearl when they describe as
"cultured pearl" because freshwater pearl is less valuable than akoya pearls
with equivalent quality.
