Smoky quartz pair with hyalite, needle formation Coronadite Hematite causes this coloration

Hematite causes this coloration

it appears as two pert semi-perfect spheres

There are some very small calcite crystals sprinkled on the piece

UV REACTIVITY microcline feldspar can have slight red fluorescence which was present in many of these specimens

Smoky quartz pair with hyalite, needle formation Coronadite Hematite causes this colorationLocale: Erongo Mountain, Erongo Region, Namibia Approx dimensions: 4 x 1. 75 x 1. 75" Approx weight: 202g 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. It can grow blocky points like the larger crystal in this pair. The two points have nice angular structure on one side and a thick layer of hyalite on the other. Paired with
