Frequently Asked Questions
What is the difference between natural and cultured pearls?

When a foreign body becomes lodged inside a mollusk, the organism develops a sac around the irritant, secreting calcium carbonate in the form of nacre to cover it. As the mollusk deposits layers of nacre, the pearl gradually grows in size. Natural pearls occur randomly in nature, without the aid of human intervention, and are quite rare. Cultured pearls are cultivated by man when technicians instigate nacre formation process.
