Fine Tsavorite and Spinel
After seeing the wealth and variety of gems on display at the Tucson gem shows, it might be easy to come away with the impression that fine colored stones are not particularly rare. Yet the truly magnificent stones are extremely rare and often have a memorable provenance. One such gem is the 18.21 ct triangular cut red spinel Bruce Bridges showed us at his AGTA booth (figure 2). According to Bridges, this magnificent gem was cut in 2007 in Bangkok from rough recovered in one astounding find in Tanzania’s Ipanko mining area that yielded several giant spinel crystals, one of which weighed in at over 50 kg. A number of other dealers at this year’s show, including Axel Henn, also displayed fine gems from this one extraordinary discovery.
