My student is molding a piece I made inspired by the creation of a pearl “A pearl started by a grain of sand that irritates and oyster…” not true! Mollusks are the ‘lungs of the water’ and filter gallons of water a day. A grain of sand doesn’t bother them in the least. So how does one oyster start a pearl and other doesn’t? To be clear, we are talking of natural pearls and not cultured in which a bead is inserted into a mollusk and then put back in the water to cover the sphere with layers of nacre. Before this technology, pearl fishers/divers had to search for the pearl in the oyster. It may have been caused by a parasite, a worm that got to the oyster through a crack in the shell. Possibly damage to the exterior causes a piece to break on the inside that would be turned around inside the shell to form a pearl. I love the idea that there are dead worms in pearls ‘worm sarcophagi’ if you will. I made this piece of silver and pearl but made the worm the necklace instead. It is titled “Distomum Duplicatum” after the worm!
