This specimen is totally composed of lustrous and translucent spheres, to 3 mm across, of sky blue gibbsite, an uncommon aluminum hydroxide. Surprisingly lightweight. This new pocket has produced some of the most colorful and beautiful examples of the species, and this was the best thumbnail I saw for sale in a whole table of the material laid out at the Shanghai show in April 2012. It is a compelte floater, all around, and seems to have a thin layer of a glossy, clear mineral (clear gibbsite , aragonite, or maybe hyalite opal) coating some spherules.

Spheres, to 6 mm across, of lustrous and slightly translucent, rich, sky blue gibbsite, an uncommon aluminum hydroxide, almost totally cover a sliver of matrix. This new find is possibly the world's best of species for intensity in coloration. Very pretty material! Very lightweight. One of the better quality pieces I saw for sale in a whole table of the material laid out at the Shanghai show in April 2012.

A thin crust of gibbsite, an uncommon aluuminum hydroxide, is emplaced on a neat 3-dimensional matrix. The spheres are lustrous, slightly translucent and reach 5 mm across. This new find is possibly the world's best of species for intensity in coloration. Very pretty material! Very lightweight. This was among the larger of the better-quality pieces I saw for sale in a whole table of the pocket, laid out at the Shanghai show in April 2012. Some small areas seem to have a thin layer of a glossy, clear mineral (clear gibbsite , aragonite, or maybe hyalite opal) coating some spherules.

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!

A vuggy matrix is host to spheres, up to 5 mm across, of lustrous and translucent, rich, sky blue gibbsite, a relatively uncommon aluminum hydroxide. From a new pocket in summer 2012

Spherules of gibbsite form solid coverings on a bit of matrix here, and they are lustrous and translucent. Beautiful new find of this rare species. Although most of the display face is intact, there are a few small spots of damage. Surprisingly lightweight, in person. This is a gorgeous, larger example from this find
