This is a gorgeous color combination of species, with a shallow surface covered in milky rhombohedrons of calcite to 7 mm in length and topped with sparkling and lustrous, emerald-green dioptase crystals to 5 mm in length. Many of the dioptase crystals are coated with a secondary encrustation of velvety, olive-green duftite. Unusual and pretty!
