Tincalconite Ps. After Borax
This is a stunning specimen that is so sharp, it looks carved. It is so rare to find them preserved like this, and complete all around as well. A cluster of large tincalconite crystals after borax, to 7 cm in length, exhibit smooth and solid chalky white faces. The interesting crystallography of the original borax crystals is clearly preserved. This is a striking, very lightweight, 3-dimensional "sculpture" of snow-white pseudomorphs of tincalconite after sharp, tabular borax crystals from the U.S Borax Mine of California. Complete all-around and essentially pristine, like porcelain in its finish! A rare and very unusual pseudomorph. Excellent material from this famous district. They are so lightweight you really have trouble believing these are natural crystals, but they are. This is just outstanding. Al Ordway's label indicates he self-collected it in 1963.
