摘要：
This report describes an egg-shaped non-nacreous pearl attached to the interior of a Crassostrea virginica (Gmelin, 1791) (in the position of the adductor scar); the State shell of Connecticut, Mississippi and Virginia, commonly known as the American or Eastern oyster. The pearl is said to have been discovered when the owner opened (shucked) an oyster for eating. The pearl is hollow and together with the shell has a gross weight of 28.204 grams. The pearl measures approximately 13.00 x 10.88 mm. The mollusc, UV/visible and Raman spectra, and microradiography results are described.
