My dad gave me these rock specimans today! The top one is petrified wood and the bottom one is Amethyst. It's so awesome to have a dad that used to be a rock hound. I have so many great specimans including a Cathedral Rose Quartz, Garnet, Blue Chalcedony, Jade, Azurite, Carnelian, Chrysoprase, Cinnabar, Citrine, Iron Pyrite, Jasper, Mahogany Obsidian, Rhyolite, Desert Rose Selenite, Tektite, and too many types of Agates to list along with a few other specimans that I'm sure that I've forgotten. All of these are cut but in raw form. He has so many more, but he's slowly giving them to me :D I love surrounding my house with all of these lovely treasures. One of these days I'll have to take a picture of each one.
