Gralex Quarry, Mont-sur-Marchienne, Charleroi, Hainaut (Henegouwen; Hennegau) Province, Belgium 3.1 x 2.5 x 2.4 cm. A REAL CUTIE of a gemmy, amber, 2.0 cm, cyclically twinned calcite crystal aesthetically set on a sliver of matrix from famous and now-closed Gralex Quarry of Belgium. The calcite is pristine and it would be hard to design a more beautiful matrix specimen. Ex George Elling Collection. |
