The melo pearl comes from the melo melo sea snail, a group of sea snails with scroll-like volute shells found along in the South China Sea. The melo pearl is a non-nacreous pearl with colors ranging from light tan to brown, but orange is the most sought-after color. Melo pearls are extremely rare, as no harvesting techniques exist.
