Frequently asked questions

How is the 18K gold price per gram calculated?

Multiply the gold spot price per troy ounce by the purity (75% for 18K) and divide by 31.1034768, the grams in a troy ounce. The figure on this page does exactly that with the live spot price.

How much will a buyer pay for 18K gold?

Less than this melt value. Refiners, pawn shops and scrap buyers deduct a margin for testing, refining and profit, so offers are a percentage of melt value. Comparing an offer with the live figure here shows how large that deduction is.

What does the 750 hallmark mean?

It is the fineness in parts per thousand: 750 means 750 parts of pure gold in every 1,000, which is 18K.
