Zircon’s common distribution and prevalence in several geological options enable it to be an essential mineral in both equally industrial applications plus the examine of Earth’s geological historical past by means of radiometric relationship.
Most zircons show a powerful absorption pattern which is really helpful for identification. environmentally friendly stones from Myanmar may perhaps demonstrate in excess of forty strains, although orange gems from New South Wales, Australia may perhaps exhibit only a few traces. very low zircon and warmth-taken care of stones Use a weaker Display screen.
