Gold & Gems Gold for centuries has been used as a standard for monetary exchange, in bullion, coinage and jewellery. The gold content of gold alloys is measured in karats (abbreviation K). A karat, when used with gold, is a unit of purity – 24 karat gold is pure gold, but usually you mix gold with a metal like copper or silver to make jewelry (because pure gold is too soft). Each karat indicates 1/24th of the whole. So if a piece of jewelry is made of metal that is 18 parts gold and 6 parts copper, that is 18 karat gold.GOLD DUST: We offer optimum quality gold dust direct from Gold Mine at competitive prices.
