Polished Mother-of-Pearl Scallop Shell Dish

A single valve of a large pearl oyster (Pinctada maxima), ground, polished, and shaped as a shallow tray or vide-poche. The thick outer crust (periostracum) has been removed to expose the smooth, golden-toned natural surface beneath, while the interior displays a luminous, iridescent nacre with characteristic concentric growth lines and a well-defined muscle scar.

Such polished shells were widespread from the late Victorian era through the early decades of the twentieth century. Frequently brought home as marine souvenirs, trade specimens, or cabinet curiosities, they were routinely mounted on silver or brass stands, or left unadorned for use on dressing tables as pin dishes and ring trays.

Unmarked, showing crisp edges trimmed to a clean fan outline, the shell rests naturally on its slight convex curve.
