Description

The crystals shows superb quality - it is water-clear, highly lustrous, all faces show marvellous texture and the grrenish chlorite phantoms (also a layer at a small area at the reverse) gives a lot of contrast to the specimen. Crystals from the locality are very rare, and colorless rock crystal is generally much more rare than smokies - so this should be high valued: for quality, for dimension, for the rare locality!
