Melo pearls are natural, non-nacreous pearls from sea snails of the genus Melo. In GIA's study, the melo pearls were yellowish orange and showed visible flame patterns with jagged edges.

What makes them distinctive

  • Color: yellowish orange in the pearls GIA examined, with no evidence of color treatment.
  • Flames: a shimmering surface pattern, which in melo pearls appeared to have jagged edges.
  • No nacre: like conch pearls, they have a porcelain-like surface.

Buying advice

Melo pearls are natural, and GIA notes that good-quality natural non-nacreous pearls are hard to find. Ask for a lab report for any valuable piece.
