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.
