White Pearl Sewing Brass Shank Buttons For Garment

The mussel's coat is stimulated by the invasion of foreign bodies (sand grains, parasites), and the epidermal cells at the stimulated area take the foreign bodies as nuclei and sink into the connective tissue of the coat. The trapped part of the epidermal cells of the coat divide and form a pearl sac. The pearl sac cells secrete pearl and wrap the nucleus layer by layer to form a pearl. A foreign body as a nucleus is called a "nucleated pearl".

When the outer epidermis is stimulated by pathology, part of it divides into cells and then separates, and is then enveloped in organic substances secreted by itself. At the same time, it gradually falls into the connective tissue of the outer membrane, forming a pearl sac and then forming a pearl. Because there is no foreign body for the core, called "seedless pearl".

Cultured pearls, based on the above principles, use artificial methods to cut small pieces of living epithelial cells (cell pieces for short) from the jacket of the oyster, and implant them into the connective tissue of the clam's jacket together with the artificial nucleus prepared by the clam shell. Relying on the nutrition provided by the connective tissue, the implanted cell pieces rapidly multiply around the artificial nucleus to form a pearl sac and secrete pearl. To produce an artificial nucleated pearl. Artificial seedless pearl is a pearl that is only implanted with small pieces of cells during the operation of the outer sheath, which forms a pearl sac through cell proliferation and secretes pearl into the sac.
