Number of employees. 1,934 (2020 [1]) Website. cambriausa.com. Cambria (keɪm-bri-ə) is a producer of engineered quartz surfaces in the United States. [2] It is located in Le Sueur, Minnesota, with additional facilities throughout the United States, and in Ontario, Canada. [3] Cambria is privately held and owned by the Davis family.
Quartz is, therefore, classified structurally as a framework silicate mineral and compositionally as an oxide mineral. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. [10] Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation ...
Herkimer diamonds are double-terminated quartz crystals discovered within exposed outcrops of dolomite in and around Herkimer County, New York, and the Mohawk River Valley in the US. [1][2] They are not diamonds; the "diamond" in their name is due to both their clarity and well formed faces. Because the first discovery sites were in the village ...
Quartzite. Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone. [1][2] Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and ...
The Spruce Pine Mining District is a swath of the valley of the North Toe River in the Blue Ridge Mountains of northwestern North Carolina. The area is mined for its mica, kaolin, quartz and feldspar. [1] Spruce Pine district is one of the largest suppliers of high-purity quartz, which is used in the manufacture of silicon for integrated ...
Jasper, an aggregate of microgranular quartz and/or cryptocrystalline chalcedony and other mineral phases, [1][2] is an opaque, [3] impure variety of silica, usually red, yellow, brown or green in color; and rarely blue. The common red color is due to iron (III) inclusions. Jasper breaks with a smooth surface and is used for ornamentation or as ...
Corian is the original material of this type, created by DuPont scientists in 1967. [1] Corian is manufactured in three thicknesses: 6 millimetres (0.24 in), 12 millimetres (0.47 in), and 19 millimetres (0.75 in). Most Corian is manufactured at a DuPont facility near Buffalo, New York. Cross-section cuts show consistent color and particulate ...
Amethyst is a purple variety of quartz (SiO. 2) and owes its violet color to irradiation, impurities of iron (Fe3+. ) and in some cases other transition metals, and the presence of other trace elements, which result in complex crystal lattice substitutions. [2][3][4] The irradiation causes the iron Fe3+.
