Description

Very rarely does native copper turn up at the Little Deer Park this being the second offerig of only two I have found in my last number of visits. The copper can be seen as small dark crystals at the centre of blue areas of secondary copper minerals in turn resting on radiating natrolite crystals. Very difficult to find material.
