A carat is a unit of weight for diamonds and other gemstones. One carat equals 200 milligrams (0.200 grams). There are 453 grams in a pound (1,000 grams to a kilogram). Therefore, if your fiancee weighs 170 pounds, you have a 385,050-carat fiancee! A karat, when used with gold, is a unit of purity-- 24-karat gold is pure gold, but usually you mix gold with a metal like copper or silver to make jewelry (because pure gold is too soft). Each karat indicates 1/24th of the whole.
24 Karat gold is the purest gold you can get in gold bullion, coins, bars or gold jewelry. Coins should originate from a Mint. Smaller items such as rings and other gold jewelry should have an assay mark, or hallmark to show the purity of the gold.

In the US and Canada the spelling karat has been adopted solely for the measure of purity and carat referring to the mass weight.
