White Metal is any alloy that is light-colored, and is used especially as a base for plated silverware, ornaments and jewelry. Some of the metals used to create this alloy are antimony, tin, lead, cadmium, bismuth and zinc. Not all of these metals are found in all white metal alloys, but are combined to achieve a desired need, such as being able to be casted and polished.
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.
