Andalusite (named after Andalusia in Spain) of gemstone quality is rare, with only small quantities and sizes available, though there is in increasing demand. Its very strong distinctive pleochroism, vitreous lustre, hardness (7.5) and clarity makes this an exceptional stone. Colour ranges from yellowish brown to dark bottle-green, dark brown or the most popular greenish red. The same stone may appear yellow, green and red. Gem gravels are found in Sri Lanka and Brazil. Other localities include Spain, Brazil, Canada, Russia, Australia and USA.
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.
