Crystal Persuasions | ScienceBlogs
The lure of minerals is irrepressible when one sees fine crystals on display. This post is the first of four in a row featuring crystals seen at rock and gem shows in Arizona. The Tucson Rock and Gem Show is one of the oldest and largest of all such shows, with famed international reputation. The images shown in these posts display fine specimens on display and available from vendors. Most photos were taken with various point and shoot cameras using available light and no special preparation for the best photography conditions.
