Realgar

Large Realgar crystal on matrix from the Bob Trimingham collection. Originally purchased in 1979 from Bart Cannon and comes with his old label that describes it as 'A fine bright-red 1 inch long thick prismatic crystal rising at a 45 degree angle from a jumble-surfaced gray sandstone matrix'. The label also indicates that one corner of the main crystal has been repaired, though it is not obvious to me where.
