Abstract
The invention provides a method for producing a sufficiently large pearl in a short time without requiring a skilled person. Genes of mantle cells of a shellfish for forming a pearl layer are incorporated into genes of monads or ultramicro organisms that generate a viscous secretion, by which pearl generating organisms are prepared. By these pearl generating organisms, pearl constituents are formed from calcium ions or magnesium ions in seawater and carbonate ions. By the viscous secretion, the pearl constituents are made to adhere to and stack onto the outer peripheral surface of a core composed of a synthetic resin, shell, ceramic, wood, or metal, so that a pearl layer is formed up.
