Description

This is a crazy group - it looks like someone took an Elmwood calcite, glued a Brushy Creek piece on it and powdered it with realgar. The big scalenohedron shows very good clarity and light yellow color - really like Elmwood. The grey smaller crystals at the top are also glossy and sharp. The lower half of the large crystal is covered with micro crystals of realgar - the calcite/realgar combination is well known from this Chinese locality - but the overall appearance of this piece is really exceptional!
