"Snowflake Mohawkite" in Quartz
Mohawk Mine, Keweenaw Co., Michigan
"Mohawkite" is a mixture of copper arsenides, including algodonite and domeykite, of variable composition. It often occurs as irregular masses in the Michigan copper ores of the Keweenaw Peninsula. In this specimen, it fills the spaces between .5 – 1.5 centimeter-sized "snowflakes" made up of radiating quartz crystals--hence the informal name "snowflake mohawkite".

Mohawkite is a rare semi-precious gemstone that occurs in only one area in the world, the Mohawk Mine in the Mohawk - Ameek area of Keweenaw County, Michigan.  Mohawkite was discovered in January of 1900 near the No. 1 shaft when they were mining for copper.

Mohawkite is a rare rock consisting of mixtures of arsenic, silver, nickel, skutterudite, and copper.
