From Jan. 31 to Feb. 5, Tucson, Ariz., will again play host to a number of international gem artists and dealers.

Hosted by the German Gemmological Association, presentations on the exhibit will be given by Drs. Ulrich Henn and Claudio Milisend. The Idar-Oberstein Group will be offering Spiessbraten, a traditional beef barbecue, served with, of course, German beer.
