Stunning Brandberg miniature Enhydro Quartz crystal measuring 44 x 24 x 13 mm. The crystal has an unusual flat pointed "arrow-like" shape, with striated markings and stepped ridges leading to the crystal point. The base has a self healed cavity extending into the crystal, seen from the underside. Of note is a cavity containing a moving bubble. The crystal has a deeply coloured Amethyst section at the base, with associated bright red Hematite and Lepidocrocite inclusions extending through out the rest of the crystal. The vitreous luster is off the charts.
