The amethyst gem clam, Gemma gemma, is a small species of marine bivalve mollusk. It is a member of the family Veneridae, the Venus clams.
It is one of the smaller species of marine clam, reaching a length of only 5 mm.[1] The shell color is whitish or greyish and suffused with purple on both outer and inner surfaces.
This species is native to the Atlantic coast of North America, from Labrador to Texas,[2] but it is now also found as an introduced species in some locations on the Pacific coast.[3]
