Amethyst, calcite, siderite

An outstanding cabinet size specimen of amethyst with dark – indigo color, steep calcite crystal with a slightly dissolved scalenohedral habit, and small crystals of siderite with gold color.

„Golden dust“ quartz – quartz with siderite

An excellent and very aesthetic specimen of large quartz crystal overgrowth by steep calcite scalenohedron, followed by the second generation of small and very shiny quartz crystals with presented just pyramidal faces. At the end of mineralization process were developed just on one side of the specimen small siderite crystals.
