Hi my name is Liz and I hoard rocks. That's right, I have a problem. If I see a cool rock, it must come home with me. I think I am in good company here with others who may have the same disease. We took a trip out to our property a few weeks ago and I came home with some beauties! They are very different from the mostly brittle rocks I have found in the mountains and desert around here. They are very dense and despite their appearance have an almost glass smooth finish.
