Analysis of FAO global statistics shows that in the past decade (from 2005 to 2014), the average annual output of Chinese pearls was 3540 tonnes (t) valued at 15 million USD. However, utilization of this process for cultured pearl production now supports industries in more than 30 countries including China, Japan, Australia, Indonesia, French Polynesia, Philippines, Cook Islands, Thailand, Malaysia, India, Sri Lanka, Myanmar and Mexico, of which China has the largest production. But particular conditions are required for loose natural pearls to form and this occurrence is rare. Pearls are formed by the secretion of nacre from epidermal cells within mollusc mantle tissue. The pearl is known as the queen of jewels, and has been used for adornment and as a symbol of material wealth throughout human history.
