18K quick answer

18K gold is 75 percent pure gold

The 18K gold price per gram is higher than 14K or 10K because every gram contains more fine gold.

This page is built around 18K gold price per gram today, 18 carat gold price, 750 gold value, and 18K pawn shop searches. Those users often need both a live melt value and a selling caution.

Because 18K is common in finer jewelry, melt value may be a floor rather than the best selling route. Branded, antique, handmade, or stone-set pieces should be checked for resale value before accepting a scrap-only quote.

Purity 75.0% 18 divided by 24 equals 0.75.
Common marks 18K / 750 Also written as 18KT or 18 carat.
Best for Fine jewelry Check resale value if the piece is desirable.

Guide

Help users value higher-karat jewelry and avoid low offers.

18K gold purity

18K gold is 75 percent pure gold. The higher gold content gives it a higher melt value per gram than common 14K and 10K jewelry.

It is often used in fine jewelry, so it is worth checking whether the piece has resale value before selling it strictly for melt.

Example: 10 grams of 18K gold

A 10 gram 18K item contains 7.5 grams of pure gold. The calculator applies the live pure-gold price per gram to that 7.5 gram pure gold content.

Because 18K contains more gold, a low buyer payout can leave a larger dollar gap versus melt value.

When to get a second opinion

If your 18K item is branded, antique, handmade, or set with valuable stones, melt value may not capture the full resale value.

Use GoldCalc for the metal baseline, then compare that with appraisals or resale offers if the item appears to have value beyond metal.

18K gold price per gram today

The 18K gold price per gram is higher than 14K and 10K because 18K gold is 75 percent pure gold. That higher purity makes every gram more sensitive to live spot price changes and buyer payout percentages.

This page is useful for fine jewelry owners who want a quick melt value baseline before deciding whether to sell as scrap, request an appraisal, or compare resale options.

18K stamps and 750 marks

18K jewelry is often marked 18K, 18KT, or 750. A 750 mark means the item is 75 percent gold by weight. This is the purity used by the calculator unless you choose a custom percentage.

If a buyer tests the item lower than 750, ask what test was used and whether the item has solder, repairs, plating, or mixed components that could explain the difference.

Why 18K needs resale caution

Because 18K is often used in higher-end jewelry, melt value may be a floor rather than the best selling route. Designer signatures, vintage demand, gemstones, and craftsmanship can all affect resale value.

If the item is plain, broken, or unmatched, scrap value may be the practical route. If it is signed or in excellent condition, compare melt value with a jewelry resale quote before accepting a cash-for-gold offer.

Example: 10 grams of 18K gold

Ten grams of 18K gold contains 7.5 fine gold grams. If pure gold were $130 per gram, the melt value would be about $975 before buyer payout. A 70 percent offer would be about $682.50 in that simple example.

Use live numbers on the page for the current estimate. The example is only a formula check so you can understand how spot price, purity, and payout interact.

18K price per gram offer comparison

Because 18K has more gold content, a small difference in payout percentage can produce a larger dollar difference than it would on a lower-karat item. A 25 gram 18K lot contains 18.75 fine gold grams before deductions, so buyer spread matters.

When checking an 18K offer, compare the quote with the 18K melt value per gram and ask whether the buyer is paying for the full solid-gold weight. Stones, heavy settings, repairs, or non-gold components can change the payable weight.

For branded or well-made 18K jewelry, also compare against resale value. A quick cash buyer may be fair for scrap, but not necessarily the best outlet for a desirable piece.

18 carat, 750, today, and pawn shop searches

18 carat gold price today, 18K gold price per gram today, price of 18K gold per gram, 18K 750 gold price, and 18K gold price per gram at pawn shop all need an 18K page that explains both melt value and selling value.

Use 18K or 750 when the item is 75 percent gold. If a pawn shop quote is lower than the live 18K value per gram, compare the quote as a payout percentage and ask how the shop handled stones, testing, and non-gold weight.
