Exposed fluorite cubes on brown siderite matrix. The fluorite measures up to 2.5 cm on the edges. The faces show a silky luster with an unusual structure. The center of the cubes is yellow with white inclusions and a blue zoning along the edges. The specimen is crystalized all around; only the bottom was extracted from the rock. On one side of the specimen the fluorite is partially covered with small lustrous elongated calcite crystals. The specimen stands in the displayed positions without any support. Very aesthetic specimen with no significant damage (some old chip on the corners).
