White gold is often plated with a thin rhodium layer to improve its appearance while sterling silver is often rhodium-plated for tarnish resistance. Rhodium detectors are used in nuclear reactors to measure the neutron flux level.hodium is a noble metal, resistant to corrosion, found in platinum-or nickel ores together with the other members of the platinum group metals.
Metal-coated crystals are natural crystals, such as quartz, whose surface has been coated with metal to give them an iridescent metallic sheen. Crystals treated this way are used as gemstones and for other decorative purposes.Possible coatings include gold (resulting in a stone called aqua aura), indium, titanium, niobium and copper. Other names for crystals so treated include angel aura, flame aura, opal aura or rainbow quartz.Aqua aura is created in a vacuum chamber from quartz crystals and gold vapour by vapour deposition.The quartz is heated to 871 Â°C (1600 Â°F) in a vacuum, and then gold vapor is added to the chamber. The gold atoms fuse to the crystal's surface, which gives the crystal an iridescent metallic sheen.rystals treated this way are used as gemstones and for other decorative purposes.
