caption_attribution_description: English: Artinite Locality: Artinite pit, Clear Creek area, New Idria District, Diablo Range, San Benito County, California, USA (Locality at mindat.org) Size: 5.9 x 5.1 x 4.4 cm. Artinite (Hydrated Magnesium Carbonate Hydroxide) forms as a crust of acicular to fibrous crystal aggregates, sometimes forming velvety balls, as with this superb specimen that was in the notable collection of James and Dawn Minette. These are California classics, though many collectors are not aware of this unusual carbonate (it looks a lot more like many silicates - certainly not a typical-looking carbonate). A really pretty example, in fine condition.

context_page_description: Artinite is a hydrated magnesium carbonate mineral with formula: Mg₂(OH)₂·3H₂O. It forms white silky monoclinic prismatic crystals that are often in radial arrays or encrustations. It has a Mohs hardness of 2.5 and a specific gravity of 2.
  It occurs in low-temperature hydrothermal veins and in serpentinized ultramafic rocks. Associated minerals include brucite, hydromagnesite, pyroaurite, chrysotile, aragonite, calcite, dolomite and magnesite.
  It was first reported in 1902 in Lombardy, Italy. It was named for Italian mineralogist, Ettore Artini.
