5.3 x 1.4 x 0.9 cm (largest). An excellent 3-piece set of quartz crystals from Namibia. The two, tall, tabular crystals are glassy, water-clear and have interesting zoning of amethyst, smoky and colorless quartz. The shorter, stout crystal is doubly terminated, water-clear with frosted termination faces and has unusual inclusions of goethite or hematite. All three crystals are pristine.
