5.2" Cut/Polished Hematite Slab - Planet Peak, Arizona

Here we have a stunning, 5.2" wide formation of hematite with quartz that was collected from a site near Planet Peak Mountain in La Paz County, Arizona. This unique hematite formation has been cut flat on both sides and lightly polished. It doesn't maintain a uniform thickness all the way across, with the thinnest end measuring .4" and the thickest end about .8" thick.

It comes with an acrylic display stand.

Hematite is a fairly common mineral, typically responsible for the red-brown colorations found in other minerals and rocks. Its chemical composition is Fe2O3, occasionally containing small amounts of titanium (variable formula (Fe,Ti)2O3). Much of the time, non-crystalline hematite specimens are the result of a transformation from limonite following loss of water.

Quartz is the name given to silicon dioxide (SiO2) and is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich environments--usually igneous rocks or hydrothermal environments like geothermal waters--at temperatures between 100°C and 450°C, and usually under very high pressure. In either case, crystals will precipitate as temperatures cool, just as ice gradually forms when water freezes. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountain formation: these veins can be hundreds of millions of years old.
