What does the 750 hallmark mean?
The 750 hallmark means the item contains 75,0 % pure gold, which is 18 karat. The rest is other metals such as silver and copper, which make the alloy harder. To estimate the value of the gold content, multiply the weight in grams by the price per gram above.
The prices shown are reference values for the gold content, calculated from the international spot price per troy ounce and converted into EUR. They do not include dealer premiums, VAT or the making charges added to jewellery. When you sell, dealers usually pay somewhat less than this reference price.
