GEMS AND GEMOLOGY

Gemology has been a fascinating hobby of mine for over 20 years, reading up “Gemstones of the World” by Walter Schumann, attending practical classes on coloured gemstones, and visiting gem mining areas. I acquired some pieces, both priced and less well known, of various colours, shapes and cuts from gem-producing areas like Burma,Sri Lanka, Thailand, Cambodia etc. These have since grown to quite a collection.

Among the 63 gems species are: traditional gemstones - corundum(sapphire,ruby), beryl (emerald,aquamarine), fancy diamond; and others - spinel, chrysoberyl(cat's eye,alexandrite), tanzanite, garnet(tsavorite, spessartite,), tourmaline(rubellite,indocolite), zircon, topaz, quartz(amethyst,citrine), chalcedony(agate,chrysoprase), feldspar(moonstone,labradorite), kyanite, peridot, kunsite, scapolite, flourite and many other lesser known gemstones. (view complete list on blog archive on the right with traditional gemstones at the bottom. click on types of interest to you.)

I'm now divesting my collection. An abbreviated description is provided below each photo, including price.

LAPIS LAZULI – STATELY ROYAL BLUE

Lapis Lazuli, Arabic and Latin for “blue stone”, is made up of several minerals, including lazurite, sodalite, calcite and pyrite. The colour varies from royal blue, lazur blue to violet and greenish-blue, but it is the intense blue with minor patches of white calcite and brassy yellow pyrite that is considered to be the best quality. Lapis, for short, has been worn since prehistoric times for jewellery in the belief that it protects the wearer from evil. Today it is used for ring stones and necklaces, as well as sculptures, vases and ornamental objects. Best quality is from Afghanistan. Other high quality locations include Burma, Russia, USA, Chile and Argentina.
