June Birthstone - Pearl
Pearls are the only gems found within living creatures, both salt and freshwater mollusks. However, most pearls on the market today are cultivated, since they now occur extremely rarely in nature. While they require special care, pearls have an enduring
appeal for jewellery, particularly as the traditional June birthstone. For a pearl to form, an irritant must get deep enough inside of the shell that the mollusk cannot expel it. As a result, the creature’s shell producing system begins coating the irritant with nacre, the shiny substance found on the interior of most shells. The thin layers of nacre create a kind of diffraction grating through which light must pass. This creates a pearl’s distinctive surface luster.
Pearl has another, unofficial, June association: weddings and, in particular, brides. This isn’t just the result of clever modern marketing. Pearls have been connected to weddings, fertility and love for thousands of years.
