Description

This specimen with fluorite and calcite comes from the 2nd cavern of the Summit Cleft. I found it in July 2021. You can also read the exact report on my homepage. The fluorite shows a silk matt surface with a light square texture. Within the fluorites there are the beautiful blue zoning along the edges which can be seen not so well in the photos. First and third photo with medium LED light as backlit!
