These are very rare clam pearls. Being natural, they are not perfectly round. They don't have the luster of pearls, but they have a glossy white color. I have kept them carefully, but I will give them to anyone who wants them. Description: Pearls (pearl-like substances) are very rarely found near the flesh or shells of clams. They do not have the beautifully iridescent layers (nacre) of Akoya pearls, and most are whitish and cloudy or irregularly shaped, but occasionally, those with pearl-like qualities are discovered. Characteristics of clam pearls: Color and Shape: White to off-white, often irregular spheres or flat hemispheres (with a nucleus). Formation Mechanism: When closing the shell, foreign objects such as sand or parasites enter the body (mantle), and the clam covers them with shell components (calcium carbonate) to defend itself, thus forming the pearl. Presence of Nacre: Unlike common pearls (Akoya pearls), they do not have nacre, so they have less strong iridescent luster. Rarity: An accidental find, like winning the lottery, with a probability of finding one in tens of thousands.
