Rich, lustrous, gun-metal colored nagyagite crystals to 6 mm cascade down onto this quartz-covered matrix. A fine specimen for a showy, display-quality miniature of this species. These are pocket crystals grown into an open cavity, and so notably these crystals have superb luster, not indicative of the acid-leaching so often used on this material to free crystals from enclosing quartz. The crystals are, for the species, unusually robust as well. I have had more pricey examples of this species but few I liked better for the overall representation of quality and display aesthetics as this piece. (TYPE LOCALITY)
