Every once in a while, you come across a stone so beautiful or unique, it takes your breath away. These are the stones that I’ve saved for this section. They are much rarer than the other stones on this site, sometimes because the main sources have been mined out, or because of the astounding colors and images captured in them, or because of their sheer size. Yes, they would be fantastic in a jewelry piece, but they are also just fine on their own, as part of a collection. These are all, of course, one of a kind.
