Rosa's heart was racing from the four cups of coffee she had just finished, but she thought she might be having a heart attack.
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.
Each bar contains 1 kilo (32.15 oz) of pure (.9999 fine gold) 24 karat gold. Kilo bars are an exceptionally convenient way of storing gold bullion. A 1 kilo bar is roughly the same size as an iPhone. If you're serious about owning raw gold, there's no better way to do it.
