Gold, A Precious Metal

Gold is a rare metallic element with the chemical symbol, AU, for the Latin word "Aurum, meaning Glowing Dawn.

The properties of Gold are unique to all other metals.

  • Pure gold does not tarnish, rust or corrode.
  • Gold can be melted and shaped into many forms
  • Pure gold has a natural warm yellow color, it is colored by other metals added to it.  All other precious metals are silver or grey.
  • Gold can be alloyed with several other metals to increase its strength.
  • Gold allows for different type of finishes; including, highly polished, satin, matte, hammered, diamond-cut and filigree.

Gold is described in terms of karatage to indicate the pure gold content of a particular item.  Karatage describes the parts of pure gold per thousand; for example, if an item is stamped (hallmarked)

  • 750 is measure for 18k gold having 750 parts of gold per thousand, 75% pure gold and 25% alloy (another metal)
  •  585 a measure for 14k gold,  58.5 % of pure gold
  •  24k gold must contain a minimum of 99.0% gold

All jewelry should be hallmarked, or called 'fineness mark'  with a stamp to indicate the value of the item and the percentage of the precious metal versus the alloy.

Gold items can be produced in a range of colors including, white, yellow, red, green, blue, black and purple.  The variations are achieved by mixing pure gold with other metals.

  • White gold is produced by alloying pure gold with white metals; nickel, silver, palladium and zinc. Nickel should not be used for jewelry purposes because it causes allergies when worn on skin.
  • Rose gold is produced by alloying pure gold with raising the ratio of copper to silver.
  • Green gold is made by adding a combination of silver, palladium and copper.

Variations in color also affect the properties of gold hardness and strength due to the different mix of alloy.
