The Auralite 23 mine in Canada produces the rarest varieties of Quartz found to date. These crystals and specimens display a multitude of different color varieties often embedded with a complexity of metallic inclusions. Assay sampling has indicated high concentrations of copper, chromium and nickel, all of which are associated metals in platinum & gold group elements. Recent research has indicated the following elements may also be present in Auralite 23: Titanite, cacoxenite, lepidocrosite, ajoite, silver, covellite, hematite, magnetite, pyrite, goethite, pyrolusite, iron, limonite, sphalerite, chalcopyrite, gialite, epidot, bornite, rutile.
