Gemstone Details

This page will be updated regularly with brief details of the gems I use in my jewellery.

Magnesite,  a member of the calcite group,  has been used in jewellery for hundreds of years and is mined around the world, including Brazil, Europe, America and Australia.  This stone is very porous and can therefore be dyed with rich vibrant colours.

Pearls are the result of self protection by the oyster or mussel coating an irritant inside the shell with nacre.  In naturally occurring pearls (the most expensive and rarest) the irritant may have been a grain of sand, but in cultured pearls an irritant, usually a small bead known as the nucleus, is is placed in the oyster or mussel.  The ultimate size of an individual pearl is determined by the length of time the nacre is left to build up.

  • Biwa pearls.   These pearls have a unique elongated shape. Originally cultivated in Lake Biwa in Japan, the term ‘biwa’ now reflects the shape.
  • Keshi pearls.  Sometimes the organism rejects the nucleus and the nacre continues to build but without the nucleus to guide it, it develops into irregular shapes and sizes of pure nacre.  It is because the pearl is composed of nacre only it has incredible lustre, but as the keshi is a a bi product of the cultivation process it technically not a pearl.
