TANGERINE (HEMATITE) QUARTZ SPECIMENS

These clusters are natural and untreated. The orange color is caused by a combination of iron, hematite, and manganese coating the surface of the crystals but also present as inclusions within the crystals themselves. Lower quality material, often with lots of surface damage, is present on the market from Brazil, but this is some of the first high quality, natural specimens we've seen from Madagascar.
