Red Glaucophane Crystal Ball 60mmThis red glaucophane crystal ball is about 60 70mm in diameter. It makes a perfect craft material when making crystal grids or terrariums! Each crystal ball is unique, although the one you receive will be similar to the one in the photos, it may not be the exact same one. So please expect a little variance. I have included pictures of multiple crystal balls so you can get an idea of this variance.
