This lot is for 2 pieces of Scottish mountain Smokey quartz. Found in the Perthshire mountains, it was picked up on our March 2025 trip. 
The two pieces have darker glassy patches on them. They are Smokey as well as white in some places. These quartz crystal chunks come from the Scottish Highlands, where Mica schist, quartz, and garnets are common but all erode away in the rain. Buying these crystals chunks means preserving Scottish rocks.
