This superb amazonite and smoky quartz specimen is from the Smoky Hawk Mine, Teller County, Colorado. Amazonite is a variety of microcline feldspar colored blue to green by small amounts of interstructural lead, and possibly affected by natural radiation over a long geological period. The Lake George/Florissant area has produced some of the finest smoky quartz and amazonite specimens in the world. This bright blue-green amazonite crystal cluster exhibits some subtle white stripes and caps caused by a late stage overgrowth of colorless microcline or albite feldspar. The specimen also includes one well-formed dark brown crystal of smoky quartz. As is common with Colorado amazonite crystal clusters, the specimen is repaired (2x) and restored (2x). Dimensions (cm): 3.5 H x 6.2 W x 5.5 D. Location: Florissant, Teller County, Colorado, USA HWAC# 53013
