Buy AumSum Merchandise: http://bit.ly/3srNDiG Website: https://www.aumsum.com Gold and platinum are used to make jewelry because they are malleable and ductile metals. Malleability is the property by which metals can be beaten into sheets, while ductility is the property by which metals can be drawn into thin wires. These properties allow gold and platinum to be molded into a variety of designs. In addition to this, gold and platinum are very rare as well as lustrous, meaning, they have a shiny appearance. These qualities make them even more attractive and enticing. Besides this, gold and platinum are noble metals. Noble metals are a group of metals which are not very reactive. They resist corrosion and oxidation. Hence, the jewelry made of gold and platinum doesn t easily lose its shine.
