Very Fine Conch Pearl
Strombus gigas or Queen Conch
A conch is one of a number of different species of medium-sized to large saltwater snails and their shells. True conchs are marine gastropod mollusks in the family Strombidae, and the most well known species is the Strombus gigas or Queen Conch. The pearls they produce are calcareous concretionsthat is they are non-nacreous and are made up of calcium carbonate (rather than aragonite which is the composition of nacreous pearls).
Several thousand snails would have to be found in order to recover a pearl as fineand as largeas this one. Symmetry can be a particularly elusive attribute and this fine example displays the most sought-after ovoid shape. Its color is evena true baby pink hueand the luster is porcellaneous. But these factors are surpassed by the quality of its flame pattern iridescenceit consistently and evenly covers the entire pearl appearing to shimmer above its surface.
Weighing approximately 17.50 carats and measuring 15.5 x 12.5 x 10.5mm
