The trade name "Auralite 23" refers to crystals containing a mixture of at least 17 minerals or elements out of a total of 23. Auralite 23 was discovered in 2007 in Canada, in the Thunder Bay area and is estimated to have formed 1.2 billion years ago. Using X-rays, 23 elements were detected in its composition in various proportions, namely: titanium, cacoxenite, lepidocrocite, ajoite, hematite, magnetite, pyrite, pyrrolusite, gold, silver, platinum, nickel, copper, iron, limonite, sphalerite, covelite, chalcopyrite, gialite, epidote, bornit, rutile, smoky quartz and amethyst, so it's a rarity!

There are also auralities on the market from Brazil, from the Espirito Santo area (Minas Gerais).
