Calcite crystals with Barite
This specimen is an impressive piece. It's large in size of course but the crystals are also very sharp and well terminated. I see only one contact near the bottom and this hardly detracts from a plate of this calibre. The surfaces are glassy and the luster is satiny. I might point out that the reddish-orange color appears to be beneath the surface and not a coating. There are sections in each crystal where the Calcite becomes almost semi-transparent due to a lack of inclusion in
that area. I suspect the mineral inclusion is Hematite and without it, this would be lesser piece.
From Torquay, South Devon, Devon, England.
