ID: CC27999
This small thumbnail from Wheal Jane, close to Truro in Cornwall, comprises of a single greyish, terminated Quartz crystal, one side of which is covered with 1 to 3 mm black Cronstedtite crystals dusted with micro-spherules of apricot-tan Cacoxenite. Do please note this is a small specimen and could be considered a micromount. Using a lens and scale, I roughly measure the Cacoxenite spheres at about 0.1 mm diameter (yes, mm, not cm). Cronstedtite is a complex iron silicate and Cacoxenite an iron aluminium phosphate. Both species are well known from Wheal Jane but are uncommon.
