Gold uses the karat ÷ 24 fraction. For a specified fineness such as 585 or 916, use that exact fineness when quoting production. The 24K row uses the theoretical 100% convention; actual trade gold may be 999 or 999.9 fine.

Jewelry is usually weighed in grams; its weight varies by design. Bullion sizes include 1, 10, and 100 troy ounces, as well as 100 g, 500 g, and 1 kg. Larger weights below are bulk calculation quantities, not necessarily individual bar sizes. Bullion sizes · Silver fineness
Non-USD values are converted from the USD metal quote using daily exchange rates; they are not local dealer quotes and exclude currency conversion fees. 1 troy ounce = 31.1034768 grams; 1 kg = 1,000 grams. These are theoretical metal content values at the displayed quote, excluding other alloy metals, supplier premiums, manufacturing, stones, freight, taxes, and retail margin. Use metal weight only, excluding stones and nonmetal parts. Quotes refresh on opening, on returning to the tab, and every 30 minutes while open. This is a periodically refreshed market reference, not a streaming or guaranteed trade price. Older and saved quotes are labeled with their timestamps.
