the type of karat
Actually you're probably asking how to value a 14-karat gold ring given a price you know for 24-karat gold.You can calculate the answer given the known value of 24-karat gold per ounce, by weighing the 14-karat gold ring to discover its weight.Then you can calculate the value of the gold using the 24-karat gold price, and divide this number by 24. Then multiply that number by 14, and you'll have the answer you want.
It depends on the weight of the starting gold. 18 karat is 75% pure gold, and therefore a 1 gram weight of 18 karat gold would have 0.75 grams of pure gold in the alloy.
The letters preceding the number indicate the maker of the jewelry. The 14K indicates the gold karat. In the case of 14 karat gold, it contains 58.3% gold.
11.1
22 karat gold is 91.6% pure. 24 karat gold is 100% pure gold, so I guess the number would be 999 or 1000.
Karat is a percentage rating of gold in parts per thousand. Karat is basicly a purity rating. 14K represents that the metal is 58.3% 24k gold or 583/1000. They determine karat rating by dividing the amount of pure gold with the total amount of gold and other stuff making up the item and multiply that number by 24.
24 karat is pure gold. 32 karat is impossible.

You'll need either the karat value (amount), or the gold's purity (one of these two is often stamped on the gold). The purity is usually stamped in parts per thousand, so (for example) 800 gold (.800) is 800 parts per thousand (4/5). The karat amount is in parts per 24, so (for example) 14 k. gold is 14/24 pure (58.33 %), 18 karat gold is 18/24 pure (3/4), and so on. 24 karat gold is 100% pure. To convert from karats to percent, multiply the karat-number of the gold by 0.04167. See the attached Related Link.
