A method for producing a cultured pearl, including the forming a green body from a calcium carbonate precursor powder, equilibrating the moisture content of the green body to a level of between about 5 weight percent and about 8 weight percent, partially densifying the green body and spheroidizing the green body to a produce calcium carbonate sphere, sintering the calcium carbonate sphere to produce a densified seed, tumbling the densified seed in fluidized calcite, placing the densified seed between the mantle lobe and the shell of a bivalve, growing a pearl around the seed, and harvesting the pearl from the bivalve. Preferably, the pearl is grown over a duration of between about 6 months about 36 months. |
