A single, undrilled natural abalone pearl measuring 17.8 carats.

Abalone pearls are considered by many to be some of the most beautiful pearls in the world, and they are also some of the rarest. Abalone pearls come from the gastropod mollusk, Haliotis. The inner mother-of-pearl shell of the abalone has an intense luster and a mixed color palette of blues, lavender, orange, green, pink and silver, in every conceivable combination. The beauty of the abalone pearl is the reflection of this color potpourri in its typical irregular shape.
