Australian pearls are produced in the South Seas. It is the region between the northern coast of Australia and the southern coast of China. A wide enough area, characterized by its warm waters, which represents the natural environment the most suitable to the reproduction of a species of oysters known as “Pinctada Maxima”.

Australian pearls formation
The formation of Australian pearls results from a defense mechanism. When a foreign body infiltrates the shell of the Pinctada Maxima, like a sand grain, the mollusc then produces a mother-of-pearl to protect its body from the intruder.
The oyster surrounds it with thousands of mother-of-pearl layers that eventually form a perfectly smooth marble preventing any injury or irritation. The color of the pearl varies according to the species of this variety: it can be white, golden, gray, cream color…
Do you know that in the nature 1 oyster in 10,000 produces a valuable pearl? The ratio is much higher with 40% marketable pearls with cultured oysters.
To reach this figure, molluscs are grafted with a nucleus, a perfect ball designed based on mold shell. They are then put back into the water for 18 months, until pearls are formed. Thus, it is possible to produce pearls from Australia in many parts of the world!
