Here are two more medium sized and delightful Thunder Egg Geode in shades of browns. Watch the video – click here. Dimensions are for the right. Each has been sliced in half but only how a low sheen polish. This means each is showing the inner most crystal structure with a different texture to the surrounding layers. I love these half pieces as you get to enjoy the outer shell as well as the inner growth rings. They are a form of agate from Queensland, Australia. We also have the South American geode versions – click here. From time to time these appear in a local prospector’s offering. As the previous three went quickly, I grabbed this one as soon as I saw it. So don’t wait around if you like it! Does either thunder egg geode excite you for your collection or someone you love?
