Lime green glassy crystals of Molybdofornacite crystals in groups to about 0.75mm scattered in spongy matrix with minor Dioptase. Excellent scope specimen and rare. The green of the Molybdofornacite is a little greener and brighter than the crystals in-hand due to the digital process. They are still, however, a very stunning green.
