In Japanese pearl cultivation, scientists have isolated strains of oysters that possess superior pearl-producing qualities. These selectively-bred oysters produce pearls of exceptional lustre and color clarity. In a process referred to as "nucleation," also called "grafting" or "seeding," highly skilled technicians carefully open live pearl oysters, and with surgical precision make an incision in the oyster's body. Then, they place a tiny piece of "mantle tissue" from another oyster into a relatively safe location. Then, they place a small round piece of shell, or "nucleus," beside the inserted mantle tissue. The nucleus is a mother-of-pearl bead made from an American freshwater mussel.
