While making a couple of marble eggs i googled “granite” and “images” and was so taken by a particular kind of granite (orbicular granite) with its gorgeous round geode like places that i decide while i am making “faux rock” eggs with egg shells and polymer clay i would try to create one that might look like orbicular granite. I think this egg (which i have just sanded to a smooth finish but not glossed) is really fun. If you want to see some awesome real orbicular granite, google it. There are not that many places in the world where such granite is found.
