Geology & Origin
Cyanotrichite is a rare hydrated copper aluminium sulfate that forms in the oxidation zones of copper-rich ore deposits. The Grandview Mine in the Grand Canyon is one of the world's best-known localities for this mineral and has produced numerous high-quality collector specimens with intensely blue mineralization. The arid conditions of the region favored the formation of a wide variety of secondary copper minerals that commonly occur together and create spectacular color contrasts. Due to its rarity and distinctive appearance, Cyanotrichite is regarded as one of the most sought-after minerals from North American copper deposits.
