What’s the difference between platinum and white gold?

White gold is a mixture of pure 24k gold with whitening metals such as nickel or palladium (plus other metals for strength). Because gold in its natural state is yellow, white gold may be slightly yellow in appearance.

Platinum is the ideal choice for diamond settings because of its white color, great strength and durability. To improve hardness, platinum is usually alloyed with iridium or ruthenium. Creating jewelry in platinum takes longer than in gold. And, because of its purity, density and longer fabrication time, platinum can be considerably more expensive than white gold.

What’s the difference between carat and karat?

Carat is a unit of weight for measuring gemstones. One carat is equal to 1/5 of a gram. For example, a 5.00 carat sapphire would weigh exactly 1.00 gram. Each carat is divided into 100 parts, often called “points”. Karat indicates the purity of gold. Pure gold is 24 karat. 18 karat is 18/24 or 75% pure gold. Sometimes 18 karat is marked “750″. 14 karat is 14/24 or 58.3% pure gold and is sometimes marked “585.”

How do 18 karat and 14 karat gold differ?

Besides the fact that there’s more pure gold in 18K, it’s heavier in weight and has a richer yellow color. It’s also available in white and pink, as well as yellow. And occasionally, 18K yellow gold is also chosen for its more malleable properties, such as a setting for a delicate gemstone.

What’s the difference between platinum and white gold?

As one of the most precious metals, platinum alloys are 90%-95% pure. Platinum is also so dense that a six-inch cube would weigh about 165 pounds.

Why is chlorine bad for gold jewelry?

Chlorine is a highly corrosive and will attack gold alloys, possibly causing cracking. Chlorine is found in bleach, household cleaners, swimming pools and hot tubs.
