Mutiara
Mutiara is the Indonesian and Malay word for pearl, a lustrous gem formed inside certain mollusks. Natural pearls occur when an irritant enters the mollusk, prompting it to secrete nacre, which coats the irritant until a smooth, iridescent sphere forms. Most pearls on the market are cultured, produced by inserting a bead or tissue into a mollusk to stimulate nacre production. The cultured pearl industry expanded globally in the 20th century, led by innovators such as Kokichi Mikimoto.
Pearls are categorized by origin as seawater (saltwater) or freshwater pearls. Major commercial types include Akoya
Beyond jewelry, pearls have cultural significance in many societies and have been used as symbols of purity
