About Precious Metal

Metal is a solid mineral element that usually has a shiny surface and generally a good conductor of heat and electricity, and can be melted or fused, hammered into thin sheets, or drawn into wires. Metals form positive ions and basic oxides and hydroxides. Many metals are quite hard, with high physical strength. When polished, metals tend to be good reflectors of light. Common metals include bronze, copper and iron whereas metals used for making jewelry, such as gold, platinum, and silver are called ‘Precious Metals’.

Alloy is a mixture containing two or more metallic elements or metallic and nonmetallic elements usually fused together or dissolving into each other when molten. For example, brass is an alloy of zinc and copper. Metals easily form alloys with other metals. The presence of even a small amount of another element in a metal severely affects its properties.
