Gold(Au) - Gold is a highly sought-after rare metallic element. For many centuries gold has been used for money, jewellery and ornamentation symbolising wealth and prosperity. Like other precious metals, gold is measured by troy weight and by grams. When it is alloyed with other metals the term carat (or karat in the USA) is used to indicate the amount of gold present. Pure gold is twenty-four twenty-fourths (24/24ths) gold, and is called 24-carat gold.
