Using, the below simple formula, you will need to convert ounces of gold to grams of gold (since gold jewelry is often listed in grams, not ounces.

In the below example, plug $1,200 per ounce (today’s gold price) into the formula for determining the base price per gram of a 14K gold chain.

Example: $1,200 / 31. 1 / 24 X 14 = $22. 50 per gram. What does this tell you? That each 1 gram of 14k gold is worth $22. 50 as far as the raw precious metals of gold are concerned. Still following?
