How is 18kt black gold produced ? Not coated?
I made the mistake of asking a question but not including the main detail. Iron is used in black gold i think 75% but does anyone know the actual details of the parts of each alloy etc
Black gold or 'grey gold' as it is sometimes referred to is a type of gold used in jewelry. Though gold is known for its warm yellow color it can be produced by various methods in differing colors ranging from white to black. Black colored gold can be produced by various methods.
[1] Electrodeposition or Electroplating using black rhodium or ruthenium. Solutions that contain ruthenium give a slightly harder black coating than those that contain rhodium.
[2] Patination by applying sulphur and oxygen containing compounds.
[3] Plasma assisted chemical vapour deposition process involving amorphous carbon, and controlled oxidation of carat gold containing chromium or cobalt.
More recently a laser technique has been developed that renders the surface of metals deep black. A so called femtosecond laser pulse deformes the surface of the metal forming nanostructures. The immensely increased surface area can absorb virtually all the light that falls on it and thus rendering it deep black.
But there is also something called "Black Hills Gold" A style of gold jewelry said to have first been created in the 1870's by a French goldsmith named Henri LeBeauold, who is said to have dreamed about the design after passing out from thirst and starvation. Black Hills gold jewelry depicts leaves, grape clusters and vines. Most Black Hills Gold jewelry uses 10K or 12K gold alloys in shades of yellow, pink, rose, and green.
The jewelry must be manufactured in the Black Hills of South Dakota in order to be called Black Hills Gold Jewelry
Yellow: natural gold is yellow anyway
Green: created by adding more silver to gold.
Rose: the more copper, the deeper the pink or rose effect.
Sorry, couldn't find the exact % mix.
