Over the time, certain percentage of gold have become legally recognized as karats. It indicates amount of gold as a percentage of the total, i.e.. 24 karat is 100 percent gold. In karated gold, there is a balance of metals in the non gold percentage called alloys. These metals provide various colors and hardness of karated gold. 18 karate gold is 18 part gold and 6 part alloys such as copper, nickel, silver or Zinc. 14 karat gold is 14 parts gold and 10 parts alloy. Gold standards vary around the world. In the United States, 18,14 and 10 karat gold are the only karats allowed to be sold as karated gold. In order to buy 14 and 22 carat, individuals need to visit sites such as 14k gold jewellery online and 22 carat gold jewellery to make purchases.
What is the difference between 14 karat and 18 karat gold ?

It is the standard for American jewelry. Few prefer 18k princess cut jewellery and few others prefer round cut jewellery.
How gold changes its color ?
Addition of elements to gold not only increases its toughness and hardness, but also changes its color. Adjusting the proportions of coloring agents provides array of colors on the market. Additional metals enhance properties such as catability, grain size, hardness, corrosion resistance, color, workability, ultimate strength and others. These additions can dramatically change the properties of the karated metal for better or worse. For example, 18 karat rose gold is 75% pure or 18 parts fine gold and 25%, of 6 parts copper. It is the rich red copper combined with the pure yellow gold that creates a warm rosy tone. 14 karat white gold is 14 parts gold and 10 parts white metal, either nickel or palladium. These white metals dominate the color, creating warm gray tone.
Explain the difference between Platinum and white Gold ?
Platinum is a precious metal that costs more than gold. It is usually mixed with other similar metals known as the platinum group metals such as iridium, palladium, ruthenium, rhodium and osmium. Platinum is extremely dense, and is much heavier than gold or silver. Platinum has remarkably high level of durability so it does not wear or tarnish like other metals. White gold is rhodium plated and it has white look as platinum, but eventually the rhodium wears off and the white gold takes its whiteness. Platinum does not yellow or tarnish and maintains its white appearance with little maintenance .
