Melo pearl facts

Melo pearls are amongst the rarest gems in the world.

They're created by the Indian Volute, or Melo Melo:  an extremely large marine gastropod from the Volutidae family, found in Southeastern Asian waters.

These large melo snails inhabit shallow waters off the coast of Myanmar, Thailand, Cambodia, Vietnam, Malaysia, the Philippines and the South China Sea.

These natural pearls are produced when an irritant, such as a grain of sand, enters the mollusk.  As a defense mechanism, the snail will coat the irritant with a calcium carbonate, over time producing a porcelain-like pearl.

The finest melo pearls are an intense orange color with visible flame structure.  This flame-like or silk-like appearance is due to a phenomena known as chatoyancy​.

Melo pearls can range in size from just a couple millimeters to over 30mm in diameter!  The largest recorded melo pearl weighs just under 400 carats!  (397.52 cts.)
