Black Gold Is a Vey Rare Colour and Is Stated In Facts About Gold
How is this made?
Black gold is created using a few techniques.
Electro-deposition using black rhodium or ruthenium is the first technique.
Controlled oxidation of Carat gold containing cobalt or chromium can also be made to create black gold. Amorphous carbon is also used some times, with the Plasma Assisted Chemical Vapor Deposition process

Facts About Gold and More Fantatic Colours
Copper creates pink and rose tones in gold.
The more the copper, the deeper will be the effect.
Greenish shades are created by adding silver to gold.
Rose gold and Green gold can be 18-karat or 14-karat but the color is stronger in the 14-karat alloys.
Purple gold. It is referred as amethyst or violet gold. Purple gold is obtained by mixing gold and aluminium in a certain fixed ratio.
Gold content is almost 79% and therefore it is qualified to be referred to as 18K gold.
Blue gold is made as an inter-metallic compound between gold and indium . The gold gets a bluish hue color with this process

Facinating Facts About Gold and It fantastic Colours
White gold is very popular right now.
It can be in 18-karat or 14-karat gold (but not in 22-karat, as it is yellow gold).
There are two basic types of white gold alloys: white gold mixed with nickel and white gold mixed with palladium.
Nickel can be mixed with gold to create a white or gray color, but some people have an allergy to nickel. Palladium is another metal used to create white gold. Palladium is better but it costs more.

High Purity Gold Reflects Infrared And These Are Known Facts About Gold
High purity gold reflects infrared (heat) energy almost completely, making it ideal for heat and radiation reflection.
Gold-coated visors protected astronauts' eyes from searing sunlight on the Apollo 11 moon landing.
Gold is also an excellent conductor of thermal energy. It is used in many electronic processes to draw heat away from delicate instruments. For example, the main engine nozzle of the space shuttle uses a 35% gold alloy.

Facts About Gold and how gold is a good conductor
Gold's physical properties of high electrical conductivity and chemical inertness make it an excellent and reliable conductor, particularly in harsh environments, where temperatures can range from -55°C to 200°C.
The use of gold in circuitry ensures reliability of equipment operation, particularly in the vital activation of safety airbag mechanisms in motor vehicles or deployment of satellites and spacecraft.No other metal is as ductile or as malleable as gold.
A single ounce of the metal can be drawn into a wire five miles long.
Gold can be hammered into sheets so thin that light can pass through.

You Should be Aware Of All The Facts About Gold And All The Properties of Gold
Facts About Gold All Properties of Gold An unparalleled combination of chemical and physical properties make gold invaluable to a wide range of everyday applications.
One of the most important of these properties is gold's virtual indestructibility.
Gold is the most non-reactive of all metals. It is called a "noble" metal (an alchemistic term) because it does not oxidize under ordinary conditions, meaning that it will never rust and never tarnish.It will, however, dissolve in aqueous mixtures containing various halogens such as chlorides, bromides, or some iodides.
It will also dissolve in some oxidizing mixtures, such as cyanide ion with oxygen, and in aqua regia, a mixture of hydrochloric and nitric acids.
