Melo Melo pearls are extremely rare and come not from an oyster or mollusk but instead from the Melo Melo marine snail, which is found in the waters of the South Chine Sea and the Bay of Bengal. Like conch pearls, the Melo Melo gem is not actually a pearl because it contains no nacre. They can be extremely large and are generally very round. The colors range from tan to dark brown. Orange is the most desirable color.
