Group of augelite crystals showing prismatic finely striated faces with different monoclinic pinacoids intercepting it. We can observe green to colorless tones, with some zoning. Faces show brilliance on transparent crystals and a dull luster in translucent ones. When the crystal is translucent, the tone varies between colorless to light greenish. The more intense green color is visible in transparent crystals. They are disposed on a rocky matrix covered by hyaline quartz crystals, some of them penetrating the augelite. These samples are from a recent finding in Mundo Nuevo mining area known as Tamboras. THE MAIN CRYSTAL IS: 1.2 x 1.2 x 0.6 cm.
