Impressive giant clam shell featuring dramatic sculptural ridges, a deeply curved interior, and a glossy white finish. Measuring approximately 12 inches across and 6 inches high, it makes a striking centerpiece, decorative bowl, planter cover, or coastal display piece. The shell has a flattened beige area on the underside that may be an applied leveling material or an unglazed base. Its exact composition is unconfirmed and it may be a natural shell with a painted finish or a highly detailed ceramic reproduction. Vintage condition with surface marks, discoloration, finish wear, natural-looking irregularities, and small edge losses as shown. Please review all photographs carefully for condition and construction.
