Lustrous, DEEP green crystals of the deepest color possible for the species and location due to chromium content, this is a fantastic display piece of a rare varietal of Grossular not found in many years. I am further told by a collector who has been there often that the cr-grossular from Thetford Mines are usually not bigger than 3 cm x 2cm, with less than 2 mm crystals. These crystals reach 5 mm in size and this piece is covered with them, complete and undamaged save around the periphery. 5 x 4.5 x 4 cm
