Gold Colours Of Your Jewelry

moneygolddiamond -I bet you have experienced in elementary school, about mixing colours, so we already know that mixing yellow and blue will produces green and mixing yellow and red will produces pink or rose. So in metals, we have the choice of mixing colour of gold like yellow (gold) with red (copper) or white/grey (all other pure metals).

Pure gold has colour like sun yellow. Another various colour come from mixing this pure gold or alloyed with metals like silver (Ag), platinum (Pt), copper (Cu),nickel (Ni), zinc (Zn), palladium (Pd), tellurium (Te), and iron (Fe). The result colours is depend on the balancing of the amount of metals that alloyed.

The colour such as Red, Yellow and Green gold are made by mixing some amounts of copper (Cu) and silver (Ag).

White gold comes from alloying copper (Cu), nickel (Ni), silver (Ag), palladium (Pd), and older way that still using zinc (Zn).

Purple Gold (have other name as amethyst or violet gold) is come up from mixing gold and aluminium.

Blue Gold that come from mixing gold and indium.

Black gold that is created by using some kind of electro-deposition techniques with using black rhodium or ruthenium, or by controlled oxidation of carat gold containing cobalt or chromium, or using amorphous carbon.

Those compounds are named intermetallic compounds. As these compound varying the colour, they changes other properties such as hardness and strenght, and tend to tarnish. Also, they tend to be very brittle, so it cannot be easily worked by conventional way in metal working processes. Just hit it with your hammer and it will come into piece !
