DVH Rare Snowflake Mohawkite Heart Cabochon Michigan Copper Ore Cab 50x42x5 (3201)

DVH Rare Snowflake Mohawkite Heart Cabochon Michigan Copper Ore Cab 50x42x5 (3201)

$ 128.99

I made this bead pendant with a really rare gemstone material called "Mohawkite" that is a mixture of silver colored, mostly copper ores and quartz.  The fractures one sees in the quartz are completely stable.  Material with the "snowflake" pattern interspersed with quartz is the most desirable.  Measurements in the title.   This material does oxidize quickly but the shiny silver finish can be quickly returned with a simple rub with a polishing cloth.  See ALL my work with custom cut focal beads, cabochons, druzys, mourning jewelry, fordite, chains, and much more in my DVHdesigns store.  

Here's some information from the online encyclopedia about it.... "Mohawkite is a rare rock consisting of mixtures of arsenic , silver, nickel, skutterudite and copper, with the formula Cu3As up to Cu6As, and the most desirable material was usually found in white quartz matrix. It has a hardness of 3-3.5 and a metallic luster. It is named after the Mohawk mine where it was originally found. Colors range from brassy-yellow to metallic gray, and sometimes will have a blue or greenish surface tarnish. These colors come from its two main ingredients, the arsenic-rich copper minerals algodonite and domeykite. Its color may resemble pyrrhotite, but unlike pyrrhotite, mohawkite is not magnetic.  Mohawkite is believed to be found only in a copper mine located on the Keweenaw Peninsula of Michigan, known as the Mohawk Mine. The Mohawk Mine is where mohawkite was first discovered, in January 1900, near No. 1 shaft when a fissure vein of copper ore was cut. Specimens of this ore were sent to George A Koenig, of the Michigan College of Mines (now known as Michigan Technological University) for analysis. The ore was believed to be an entirely new mineral and was named mohawkite by Koenig. A reanalysis of the material in 1971 found it to be an intimate mixture of copper and nickel arsenides and the mohawkite name was discredited as a mineral species."
