This is a dramatic and rare, nearly-colorless gwindel from the classic Swiss locality for deeply smoky gwindels! This crystal is a single twisted quartz of the classic style, with no damage and complete all around. It was not, as most are, broken off matrix leaving a gash on the bottom. Rather, this is a floater with a bit of matrix attached to the bottom of the quartz, also terminated (if ingrown with matrix). The twist on this one is very pronounced and dramatic! The shots made to show the twist show a pale green tint that is not there in person, though.
