Crystallized, white feldspar is the matrix for this specimen which has a cluster of lustrous, black, schorl crystals to 2.5 cm across, upon which are emplaced glassy and gemmy, intensely-colored aquamarine crystals to 3.25 cm in length. The overall stark contrast of crystal form, color, and texture is very interesting. A druse of bubbly hyalite opal covers a portion of the schorl crystals. Like many pieces in the pocket, regrettably the terminations of the aquas do exhibit minor abrasions; but in context, I can live with it for the overall aesthetics featuring such well-defined and isolated crystals.
