• Gold

  Gold is a highly sought-after precious metal which occurs as grains in rocks.  It is a dense, soft, shiny, yellow metal, and is the most malleable and ductile of the known metals.  The gold content of jewellery alloys is measured in carats (k), pure gold being designated as 24k. It is, however, more commonly sold in lower measurements of 22k, 18k, 14k and 10k. A lower "k" indicates a higher percent of silver, copper or other base metals in the alloy, copper being the more commonly used base metal.  Although the price of some platinum group metals can be much higher, gold has long been considered the most desirable of precious metals.  Gold has been used as a symbol for purity, value, royalty, and particularly roles that combine these properties.
