A Mabe pearl is a worked and assembled blister pearl (attached to the shell). It is typically of hemispherical shape, and is grown against the inside of the oyster's shell, rather than within its tissue. Small blister pearls are commonly found in nature. Mabe Pearl has been used throughout history as a gemstone for use in Earrings as it can be more perfectly matched into pairs than many of the round earring gems.
Genuine natural cultured Pearl. An organic gem produced as calcareous concretions within the soft tissue (specifically the mantle) of a living shelled mollusk or conulariid. Mother-of-Pearl or nacre is the naturally occurring lustrous layer that lines mollusc shell oysters in the family Pteriidae and freshwater mussels in the families Unionidae and Margaritiferidae. The "mabe" (irregular) Pearl is grown through the insertion of an implant, under a flap of the mantle and next to the mother-of-Pearl interior of the shell. Composed of calcium carbonate (CaCO3) mainly aragonite or a mixture of aragonite and conchiolin calcite “nacre” in minute crystalline form, which has been deposited in concentric layers. Nacreous and iridescent and guaranteed to be free of plastics, synthetic materials, dyes or artificial colours.
