Have a first-hand look at the GL Gem Spectrometer and its use;  we will  have Dr. Bill Hanneman’s new booklet titled “Pragmatic Spectroscopy for Gemologists” on sale (60 pages, price $ 20.00). All present and future GLGemSpec users will receive a free copy.

I will be giving a presentation about the “GL Gem Spectrometer and Advanced Gem Testing” at the Arizona Hotel during the “ISG Lab Updates and Reports” session scheduled for Friday, February 4 from 8:00 – 9:30 am.

Tudo sobre diamantes

Tudo sobre diamantes

Russian  Alexandrites

By Mario del Rey.

This book would make an excellent text-book if it were translated into English. For our Portuguese speaking readers a brief synopsis:

‘Tudo sobre diamantes’ contém noções básicas de Mineralogia e Gemologia e aborda os diamantes em seus principais aspectos – características; propriedades; origem; pesquisa; prospecção; exploração e extração. O livro trata também do talhe, da avaliação e do comércio de diamantes.

It can be ordered here.

By Karl Schmetzer

In this book the author presents an historical overview of the discovery of Russian alexandrites in the Uralian emerald mines, the naming and historical use of alexandrites and their appearance and display in mineralogical museums and the gem trade.

Mineralogical and gemmological properties are thoroughly explained and numerous photo-micrographs of inclusions and growth patterns in faceted samples are presented.

It can be ordered here.

Synth. Emerald Coloured by Copper

Synth. Emerald

A GLGemSpec user sent us two spectral files of synthetic emerald with an interesting observation. Both emeralds appeared to be the hydrothermal type but one showed Cu content (750 – 760 nm) and the other one did not.

After reading the article (PDF) “A new type of Tairus hydrothermally-grown synthetic emerald, coloured by vanadium and copper” we had an answer. The other stone was purchased as a Biron synthetic emerald and fit the inclusion patterns.
