If you would like to know how to calculate the metal price and do the math read on, if not skip to next paragraph. The formula used to calculate the price is the metal price(the daily spot price) multiplied by purity(the true noble metal content) times weight(can be in ounces, pennyweights or grams). The purity is the karat of gold or percentage of noble metal (gold, platinum, silver). 24 karat is pure. 10 karat is 10/24 or.410 gold and the balance of weight is the alloys. 14 karat is 14/24 or.583 gold and 18 karat is 18/24 or.750 gold. Platinum most of the time is 90% pure and 10% alloy. Silver jewelry is usually sterling, which is.925 pure. The three units of weight used with precious metals are troy ounces, pennyweights, and grams. The troy ounce is equal to 20 pennyweights (dwt) or 31.15 grams. So here is an example; say the spot price of gold is $300 and a 14K ring weighing 10 grams would work out like this. $300 (spot price) X.583 (the fineness of gold) equals $174.90 per ounce divided by 31.15 (troy ounce to gram) equals $5.63 per gram times our ring of 10 grams equals $56.30. Just remember to subtract some refining cost and profit for the dealer and you can find out the intrinsic metal value for your jewelry.
