Black gold is commonly used in jewellery manufacture. It can be produced using a number of methods using the metals rhodium, ruthenium, chromium and cobalt.
The metal that makes up pure gold is gold and nothing else. Gold is a metallic element found in its raw form. Sometimes other metals are mixed with gold like silver for jewelry.
9 carat gold is an alloy made up of 37.5% gold, with the remaining 62.5% composed of other metals. Common metals used to create 9 carat gold include copper, silver, and zinc. These metals are added to gold to increase its durability and strength, making it suitable for jewelry making.
Black metals are typically composed of iron and carbon, with small amounts of other elements such as manganese, silicon, and sulfur. These elements give black metals their characteristic dark color and strength.
Yellow gold is typically a mix of 75% gold and 25% other metals. The additional metals used in yellow gold alloys can include copper, zinc, silver, and nickel. For a 10% composition, one of these metals would make up a smaller portion of the alloy.
Gold is an element, not a compound or molecule. It is a pure substance made up of only gold atoms.

Gold will typically turn black when mixed with a different type of alloy. Bleach and chlorine can turn yellow gold black if it comes in contact with the gold.
Pure gold is too soft to be used in everyday jewelry, so it is alloyed with other metals to make it stronger and more durable. Pure gold is 24 karat, and 14 karat gold refers to an alloy of gold that contains at least 58.3% pure gold by weight. The balance is made up of other metals to give it strength.
14k gold contains 58.3% pure gold, while 18k gold contains 75% pure gold. The rest of the composition is made up of alloy metals like copper, silver, and zinc to provide strength and durability to the gold jewelry.
18K gold is made up of 75% gold and 25% other metals, while 22K gold is made up of 92% gold and 8% other metals. 22K gold is purer than 18K gold, but it is also softer and more susceptible to scratches. Visit DAR Jewellery in COIMBATORE.
