Pearls are the only gems produced by living creatures. They are organic, created inside living mollusks.
Pearls are renewable. One mollusk can produce multiple gems at a time, can be grafted more than once – up to three times for high-quality mollusks – and mollusks also reproduce. Pearls take only a few years to form, not the thousands of years it takes for other gemstones to form.
“Pearls are unique – they are the only renewable gemstone in the human timescale,” says Dr. Saleem Ali, director of the Centre for Social Responsibility in Mining at the University of Queensland, Australia.
Regardless of whether they develop in nature or are cultured, pearls are formed in fragile ecosystems. The water in which the mollusks live must be clean and unpolluted, and marine life needs to be healthy. Pearl oysters are remarkably sensitive organisms. The healthier the oyster, the less likely it is to reject the nucleus or to be affected by a disease and other environmental stresses, and the more likely it is to produce high-quality cultured pearls.
A pearl farmer who cares about the long-term health of his farming operation must use environmentally-responsible farming practices to produce high-quality pearls now, and …Read More
