The Urals of Russia are known for fine quartz, some of it so transparent and fine that not only does it form great specimens, but also provides material for glass-clear carvings. What makes the crystals on this specimen interesting, however, is not clarity, but a coating of micro-quartz or calcite that has been deposited only on selective faces, giving the crystals an unusual banded appearance. I have not seen a Russian quartz specimen of this style before.
