Locality: Minas Gerais, Brazil. Size Class: Large Cabinet. Collection: Schertz Collection. Quartz is usually colorless, or purple (amethyst), yellow-orange (citrine), or dark (smoky). This unique specimen falls somewhere outside those normal definitions and is colored a faint red/orange by minute inclusions of hematite in the surface layers. In person, this is very beautiful, as the eye sees that layer as a stronger color than in the photo, and then sees through into the gemmy depths of the crystals inside. They reach 15 cm in length. 6.6 pounds. Size 24.0 x 16.0 x 13.7 cm.
