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).

AMETHYST (QUARTZ) – REGAL PURPLE: PROTECTION AGAINST DRUNKENESS


Amethyst is the most highly prized stone in the quartz family as the choice for jewellery. It comes in shades of purple, lilac or mauve. The name means “not drunken” (Greek), as amethyst was traditionally worn as an amulet against drunkeness, and to instil a sober and serious mind. Amethyst is dichroic showing a bluish or reddish purple tinge when viewed from different angles. Usually clean, it is often faceted as a mixed- or step-cut. (Its inclusions look like tiger-stripes, thumb-prints or feathers.) Amethyst is found in alluvial deposits or in geodes. Brazil is the chief source though it is found in many countries in all continents. It is the birthstone for February.
Shown below are amethyst faceted into different shapes, cut en cabochons and carvings of people, animals and flora/fruit.
