Fredos gems: TOURMALINE – THE GORGEOUS BLUE, GREEN and DICHROIC

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 – THE GORGEOUS BLUE, GREEN and DICHROIC

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. The name comes from the Sinhalese Turamali, meaning ”stone with mixed colours.” Other locations are Russia, USA, Madagascar, Brazil and East Africa. It is also the birthstone for March.It is a beautiful and hard (7.5 MOH) stone very suitable for jewellery. In this post, I am pleased to my collection of indocolite (blue), verdite (green), and dichroic (green and yellow) ie when viewed at different angles.

Indocolite – as gorgeous blue and bluegreen as the seas
