De-Mix Quarry, Mt. St-Hilaire, Quebec, Canada.  Ex. Dr. Steve Chamberlain collection.  Bright orange red example of this fine material measuring 3.7 x 1.2 x 1.1 cm.  Good damage-free crystal with heavy backside contact.  Translucent, transparent in areas, with luster that is excellent on some faces and blocked by coatings on others.  Minor associations and overgrowth dominate one side.  These specimens are beginning to get difficult to find, even for someone like myself who has a focus on, and many contacts for, Canadian minerals. $120
