This new find is possibly the world's best of species for intensity in coloration. Very pretty material! Very lightweight. This is one of the most aesthetic pieces from a summer 2012 pocket, which I saw for sale laid out at the Shanghai show in April 2012. A thin layer of spheres, to 7 mm across, of lustrous and slightly translucent, rich, sky blue gibbsite, an uncommon aluminum hydroxide, aesthetically cover its matrix. Some small areas seem to have a thin layer of a glossy, clear mineral (clear gibbsite, aragonite, or maybe hyalite opal) coating some spherules. Beautiful display specimen!
