Tahitian Pearl Hardness
07-22-2011, 01:06 PM


The surface quality of a Tahitian pearl is relatively soft, rating about a 4 on the Mohs scale. (Soapstone rates a 1 as the softest, while diamonds rate a 10 as the hardest.) This means that a sharp object can mark the surface, while a fingernail cannot.
