Liroconite - Sold

Liroconite is a rare copper aluminum arsenate. While first described by Count Bournon in 1801 and illustrated by Rashleigh in 1802, its modern name comes from Beudant (1832). The mineral name combines Greek roots leiros for pale and konis for powder, denoting its pale streak. Most Cornish liroconite came out in the nineteenth century; due to its intense color, liroconite ranks among the most desirable of copper species. Berry (1951) provides a good background for the copper arsenate minerals.

This is a narrow vein section of crystalline liroconite. In cavities, it forms crystals to 2 mm. It is difficult to find affordable specimens of this species. This specimen was part of the Charles Trantham (1936-2020) estate.
