Penelope’s Pearls

Description

Excerpted from the website:

Throughout history, pearls have been highly prized and sought after, worn by rulers, emporers and royalty. Until the late 19th century, all pearls were truly natural pearls – found by divers opening wild oysters to see what treasure may lie within. Pearls are formed when a substance, or irritant makes its way inside the oyster’s shell. The oyster responds to the irritant by laying down layer upon layer of nacre on the surface of the irritant. Nacre is the iridescent substance found within the oyster’s own shell – true mother of pearl. The shape and beauty of the resultant pearl is dependent on the thickness and quality of the nacre. Pearl culturing began in Japan in the late 19th century when it was discovered that the oysters could be artificially implanted with a small bead – usually made of clam shell. The oyster responds to the implant by laying nacre upon this bead (or nucleus) over the following years, producing a pearl which will be more or less round in shape.
