February’s birthstone is Amethyst, a beautiful richly coloured transparent to semi-transparent gemstone, ranging in hue from pale lilac to deep purple grape. It is the most highly valued stone in the quartz group, the most important deposits being found in Brazil. Silicon dioxide is its basic composition, coloured by traces of manganese, titanium and iron. Its name means not drunken in Greek, and was worn as an amulet against drunkenness.

I use amethyst in a number of pieces of jewellery; plain individual colours as shown in the photographs above, as well as mixed with other gemstones and glass beads to give a rich texture and colour to unique earrings and bracelets.
