This druzy, also called "Cobaltoan" or "Cobaltion," comes from the Congo in Africa. The pinks are natural, not dyed or enhanced in any way. This material is extremely high quality and fairly rare. These pieces have beveled edges to make bezel setting easy. With each new set of rough, the colors vary. The best thing to do is scroll up and down to get a sense of the difference in shades. The mauves are distinguished by a lavender cast to the pink color. The intense colors are the rarest, as are the larger pieces because the rough usually comes in small chunks. Important note: All the colors of these pinks are totally natural: They are untreated, uncoated, and undyed. Unpolished backs of smooth whitish matrix.
