Just a teaser Tucson post: my favorite giant gem from the GIA display at AGTA GemFair Tucson this weekend. Kunzite is a pink variety of spodumene, named after U.S. mineralogist G. F. Kunz, who first described the gem in 1902. (Sadly this picture lacks scale — bad geologist! — but the gem looked to be over two inches in diameter. Very nice!)
