Description

Super „French-Classic“. Well defined rhombohedral crystals formed this very aesthetic floater. The crystals are sharp all around and show snowy white color. Grains of quartz are inter grown to the faces, each grain shows micro lustrous faces. The specimen came out a cave, which was discovered in 1891. Calcite is the only mineral from the locality and material is rare and hard to obtain. Hard to photograph, better in person and very showy 360°.
