In 1916, Kikichi Mikimoto harvested the first big lot of cultured akoya pearls in Ago Bay, Japan. These Japanese Pearls were in contrast to any the world had recognized. These were whole pearls with a mother-of-pearl nucleus produced by a culturing method known as grafting. A small bead was placed in the host oyster’s reproductive organ along with a small piece of donor mantle tissue – the catalyst of pearl sac creation and nacre deposition – the formation of a pearl.

Whilst shape is an important worth manifestation of other sorts of cultured pearls like freshwater and Tahitian, akoya pearls are usually really round. This is because of the flawlessly spherical bead inserted in to the oyster. Nacre is transferred round the bead and a lot akoya pearl production is circular because of this.
