Calcite - classic British
Bigrigg mine, West Cumberland Iron field
3.1 x 1.7 x 1.6 CM (small miniature/ large thumbnail (toenail))
A clear sharp single scalenohedron from the famed Bigrigg Mine. From an older European collection this is at least 80 years old but likely much older. There is a number attached that could be removed if desired. Quite clean by naked eye but some contacts and rough bits found with magnification, all under 1mm. Not perfect but looks it, and not expensive as is often the case with these old finds.
