A few small druses of tiny Olivenite crystals line pockets in the quartz base of this large thumbnail specimen. These crystals do not exceed 0.1" (3 mm) in length but are in excellent condition due to their small size and their protective surroundings. The crystals are a bit too small and tightly arranged for one to easily study their orthorhombic prismatic forms with a loupe, but their form seems good, anyway. All have the standard dark olive-green color and vitreous luster of the specie, and all are transparent and dimly to moderately clear. A small amount of what appears to be massive, pale green malachite is also present.
