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.

APATITE – THE ASPARAGUS STONE

Greek for “cheat” because it can be easily confused, Apatite is a not hard (5 MOH) and seldom faceted as a gemstone, except for collectors, However when cut correctly, stones are bright, vitreous,  with strong colours. Usually, it is cut en cabochon for cat’s eye effect because of its strongly pleochroic. Occurs in colourless, yellow, blue, violet or green. Spanish apatite is called “asparagus stone” due to its yellowish green colour. Also found in Burma, Sri Lanka, Brazil etc.
