Ajoite is a rare copper-based mineral that appears in specimens almost exclusively as inclusions inside quartz crystals. Most often, as here, the crystals are polished to give a better view of the ajoite, as the crystals are generally milky. This one is very richly included with ajoite, so it displays a pretty blue-green color.
