I find the JOGS show to be pretty beneficial- especially if you make jewelry... This particular show is not open to the public, only the industry. There are hundreds of exhibitors under the same roof at this show, and it takes me a few days to get through everything. Here's more info for you: http://jogsshow.com/ You can per-register with your tax info.
The Tucson Gem and Mineral show is actually many shows all going on at the same time, all over the city (43 shows this year). Hope you have a great time and that info helps!
I grew up in Tucson, so no wonder I love gemstones, lol.
