Turquoise on Quartz
Miniature, 5.0 x 4.6 x 3.0 cm
Bishop Mine, Lynch Station, Campbell County, Virginia, USA
Ex. Rice Northwest Museum

For sheer richness of color and coverage, one of the best I have seen, clearly old material from this important locality for crystallized turquoise, which seems to be rare in nature for some reason compared to its lapidary cousin.
