Brown Double-Terminated Twinned Calcite from Tonglushan Mine, Hubei, China

This is a very unique calcite twin with cool brown inclusions that follow the crystal shape. This piece was collected from a local miner whose family have been mining there for three generations. It came out long time ago and was mislabelled as “red quartz” at the time I acquired it.

All weights and measurements of the piece are approximate.
