Aggregate of very sharp tetrahedral crystals, bright with a dark brown color and with small parallel Quartz aggregates and a strongly flattened Calcite crystal with its contour complete. They are between transparent and translucent, as the picture under intense light shows, and this confers a special quality to the samples from this cavity. The sample has been analyzed showing dominant Helvine forming a solid solution with Genthelvite.
