Sodalite is a rich royal blue tectosilicate mineral widely used as an ornamental gemstone. It is a member of the sodalite group with hauyne, nosean, lazurite and tugtupite. A light, relatively hard yet fragile mineral, sodalite is named after its sodium content; in mineralogy it may be classed as a feldspathoid. Well known for its blue color, sodalite may also be grey, yellow, green, or pink and is often mottled with white veins or patches.
Imitation Rhodium uses a similar-looking material to substitute for rhodium. It makes the jewelry more affordable, but at the same time keeps the same appearance and quality as a rhodium coating.
