Understanding Gold Alloy Features From Thermodynamic Phenomena

The colored gold alloys are generally a ternary matrix of three elements such as gold, copper and silver. Their association is so favorable and stable that most natural precious nuggets found around the world reflect this general composition. The variable content of copper and silver not only dictates the color but also a great part of the metallurgical behavior of the gold alloy, even if the presence of other additives is commonly required to improve the opto-mechanical characteristics to the level demanded by the modern market.
