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). Example 2:"sa (type sapphire), ov(shape oval), dpbl(colour deep blue), af(origin Africa), 4.43(weight in carat), (11.3x10.2x4.6mm)dimension LxWxD, ec(clarity eyeclean), 1k(price US$1000)".

Personal viewing can be done for friends in Singapore.

Those outside Singapore, purchase can be secured via registered post upon payment in USD(or Singapore equivalent) via paypal, money/postal order, account transfer/cheque (Singapore) or other mutually agreed arrangement. Do have a look and contact me for any other details.

Happy viewing!

SAPPHIRE (CORUNDUM) GREEN, COLORLESS, BI-COLOUR, COLOUR-CHANGE, CARVINGS, BRIOLETTE.

Sapphires come in all colors though people tend to associate it only with the color blue (depicted earlier). I have also shown in the previous post the red, pink, purple, orange and yellow sapphire and the very rare padparadscha (pink-orange). Besides adding the green and colourless (white), this post also shows the bi- and multi-coloured, the rare colour-change sapphires, carvings and briolettes. Happy viewing!
