I tried to photograph a purchase today, but gave up. I volunteered to work at the Houston Gem and Mineralogical Society annual show yesterday and today. (I'm a member.) While there too much shiny stuff. Rocks real shiny rocks. Look at the shiny rocks. Must buy some shiny rocks. Anyways I went ahead and picked up a small parcel of opal, a couple coprolite slabs (fossilized Dinosaur poop ), a trilobite, fossil leaves, fossil shark tooth, and a couple geodes. They main thing I was trying to photograph was the opal but a rough parcel is about impossible to get a good picture of.
