FREQUENTLY ASKED QUESTIONS ABOUT AUSTRALIAN SOUTH SEA PEARLS

Posted by Francisco Javier Fernandez Sanchez on

Posted by Francisco Javier Fernandez Sanchez on

Mabe Pearl or Cultured Blister? A pearl is a concretion of biomineralized aragonite and/or calcite with minor organic matter (conchiolin) produced inside a pearl sac in the interior of marine or freshwater molluscs. A cultured pearl is basically the same, but formed with human intervention inside a cultured pearl sac. The so-called "mabe pearls" are not however, technically, pearls in the sense that they do not grow inside a pearl sac. In fact, these are protuberances in the shell’s nacreous interior that form as a consequence of a culturing process, being defined as cultured blisters, that are worked, cut from...
