NATIVE COPPER

Tetrahexahedral Crystals White Pine Crystals

The greatest Native Copper Ore Deposits ever found anywhere in the world and mined profitably were those of the Keweenaw Peninsula of Michigan's Upper Peninsula. The Michigan Native Copper mineral deposit occurs in a belt about 110 miles long with a average width of around 10 miles. The Copper mineral occurs in amygadaloids, conglomerates and fissures, and has been found in size from microscopic grains to very large masses (Mass Copper) of up to around 1,200,000 pounds. Float Copper is found in mass throughout the midwest and was deposited by the glaciers that moved the Copper masses from the Michigan Copper Country. Native Copper sometimes has Silver Inclusions and is locally called a Halfbreed. Native Copper has been classified into 14 different Copper forms of occurance and can occur in 6 Copper crystal habits.

Metaphysical Properties

People interested in metaphysics and CRYSTAL HEALING tell us that copper is effective in COMBATING LETHARGY, plus helping overcome passivity, restlessness, excitability, and non-acceptance. It can STIMULATE INITIATIVE , optimism and diplomacy, and conveys the message that there is no need to search for love in life. It emits a PHILOSPHIC ENERGY, free of orthodoxy and bias. Copper provides a HARMONIC CONNECTION between the physical and astral bodies and aligns the subtle bodies. It has been used to amplify and TRANSMIT THOUGHT. It is said to be a BESTOWER OF GOOD, bringing benefit and "luck" to the user.
