I can‘t stop playing around with tanzanites. What you see here is called pleochroism: the mineral has different colors along the different crystallographic axes, made visible by rotating in in front of a computer screen (polarized light source). Typical colors are blue, violet, yellow, but also pink, green and colorless is possible. No other mineral displays this phenomenon so well pronounced and this, among other things, makes tanzanite (or zoisite as the mineral species is called) one of my all time favorites.

Cutting small stones is sometimes even more demanding than large stones, especially if the material is rather soft. I had to cut a moonstone (from Ziller valley, Tyrol) for a client´s ring in a full brilliant cut with perfect meet points: 2.9 mm or 0.075 ct. Looking forward to cutting some larger stuff again ;-)

This Burmese ruby came in for a recut. Scratches, a dull surface, completely asymmetrical and a huge ding in the pavilion. Weighing in at 2.26 ct the customer wanted the gem to stay above 2 ct, thus a complete recut was impossible. So lowering the girdle, making the shape a bit more symmetrical, and cutting a steeper, well polished crown to hide the ding on the back. Job done with 2.1 ct remaining ;-)

Finished some sapphires for a customer. 2 had to be a perfect match for earrings, thus I split the elongated rough into two parts. The other stone is for a pendant. Starting from 5.6 and 5.4 ct the stones ended up at 4 ctw, the large one slightly above 2 ct. Rough was sources from our friends at - always a good place to find exception rough.

Sometimes a piece of jewelry comes in with the task to identify the gemstone(s), in this case if it is an aquamarine. Silver, the age and the clarity are suspicious and a final proof is obtained by using UV light. The red fluorescence identifies the center stone as synthetic spinel - no further analysis needed.

I did a gemcutting demonstration at the booth this year. Despite the rough setup and bad light I was able to cut a nice tourmaline trillion. Faceting is so much fun - everyone should try at least once!

With so many new followers I thought it’s time to reintroduce myself. I am gem Cutter (USFG certified Grand Master) and scientist (professor for chemistry) and focus on the education in terms of gemstones and their identification. If you are in Tucson next week Look out and say hi!
