Gold is graded in what is called the “karat system”.

In the karat system, pure gold is expressed as “24 karats” (24k). The gold content of any item depends on the proportion of gold it contains.

  • 9k = 9/24 or 37.5% gold. Also indicated as .375
  • 14k = 14/24 or 58.5% gold. Also indicated as .585
  • 18k = 18/24 or 75% gold. Also indicated as .750

In Australia, as well as any civilized country in the world, legal regulations require the marking of gold jewellery to protect the public against fraud.
If, for example, the jewellery item is stamped 14k it cannot be less than 58.5% gold or the maker could be charged for fraud or counterfeiting.



Sterling silver is an alloy of silver containing 92.5% by mass of silver and 7.5% by mass of other metals, usually copper. The sterling silver standard has a minimum millesimal fineness of 925.
Fine silver (99.9% pure) is generally too soft for producing functional objects; therefore, the silver is usually alloyed with copper to give it strength while preserving the ductility and beauty of the precious metal. Other metals can replace the copper, usually with the intent to improve various properties of the basic sterling alloy such as reducing casting porosity, eliminating fire scale, and increasing resistance to tarnish.



When used in jewellery, platinum is commonly alloyed (900 or 950 platinum) with cobalt, iridium, or ruthenium for increased hardness. For a jewellery piece to be labelled as “platinum” or “PLAT” it must have a “fineness” (millesimal fineness) of at least 95% pure platinum. If the fineness falls below the 95% mark, it must be labelled “IRIDPLAT” which would indicate a platinum alloy with at least 10% Iridium. Platinum is graded as: 850, 900, 950, and 999, which is identified and stamped using the precious metals hallmarking system. However, Platinum 950 is the most common purity for platinum jewellery in Australia and around the world.
