Cryolite Francon Quarry, Montreal, Quebec, Canada. Ex. Dr. Steve Chamberlain collection. Don Doell collector, 1978. A fine example of this rare material in a large octahedral crystal with others (highly etched others) on a matrix of what appears to be calcite and possibly magnetite. Main crystal is 1 cm on edge and the entire piece is 3.5 x 2.5 x 3 cm. No damage but the crystal is not fully formed. Exceptional example for Francon! $100
