What is Karat
Karat is an indicator of gold purity. Pure gold is 24 karat. 18 karat is 18/24 or 75% pure gold. Sometimes 18 karat can be marked “750.” 14 karat is 14/24 or 58.3% pure gold and can be marked as “585.”
As one of the most precious metals, platinum alloys are 90%-95% pure. Some argue platinum to be the ideal choice for diamond settings due to its white color, strength and durability. Creating jewelry in platinum usually takes longer than in gold. Due to its purity, density, and longer fabrication time, platinum can be considerably more expensive than white gold.
White gold is a mixture of pure 24k gold with whitening metals such as nickel or palladium, as well as other strengthening metals. As the natural state of gold is yellow, white gold may appear slightly yellow.
