Smoky quartz point with hyalite Spider jasper with intricate growth patterns acrossLocale: Erongo Mountain, Namibia Point length: 4. 5" Approx weight: 208g Smoky quartz from the Erongo region is typically a quite dark brown black color, with lower clarity due to natural inclusions, and a flat surface luster caused by etching.
