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. Example 1: m2(size ref) tq(turquoise gem) ov(oval shape) plgnbl(pale greenish blue colour) afg ( Afghanistan country) 3.82 (carat weight) (18.7x8.5mm)(dimensions LxW) in mm) op (opaque clarity) 175 (USD 175 price) 10b30 N18(ref no and location).

TOURMALINE – RUBELLITE (RED AND PINK) – RUBY AND ROSE

The Tourmaline family refers to a number of related species and varieties with the same basic crystal structure. Their colour range from colourless, pink, red, yellow, brown, green, blue, violet, to common black and the famous multi-coloured. It is a beautiful and hard (7.5 MOH) stone very suitable  for jewellery. It has been known since antiquity in the Mediterranean region. However, the Dutch imported it only in 1703 from Sri Lanka and gave it the gem a Sinhalese name, Turamali, meaning ”stone with mixed colours.”  Other locations are  Russia, USA, Madagascar, Brazil and East Africa. It is also the birthstone for March. Below. I am pleased to display my wonderful red and pink (rubellite) collection.

Rubellite – the red beauty - named after the ruby
