Each line is weight times the published rate for that carat, rounded to the cent. The “gold content” column is weight times fineness: it is what a refiner recovers, and it is why 4 g of 18ct outpays 3 g of 9ct by so much.
Step 1: weigh it
Use a digital scale that reads grams to one decimal place; a kitchen scale is fine for an estimate. Weigh each item separately. Remove anything that is not gold where you can: a watch movement and strap, a large stone if it is loose. Where you cannot, note it; we weigh stones out on the bench. Hollow items (rope chains, lockets, puffed hearts) weigh less than they look, so weigh rather than guess.
Step 2: find the carat
Look for a small stamped number, usually inside a ring band, on the clasp of a chain, or on the back of a pendant or earring post. A loupe or a phone camera on zoom helps.
| Mark | Carat | Gold content | Typical of |
|---|---|---|---|
| 375, 9ct, 9K | 9ct | 37.5% | Most Irish and British jewellery |
| 585, 14ct, 14K | 14ct | 58.5% | American, continental European |
| 750, 18ct, 18K | 18ct | 75.0% | Better rings, Italian chains, French and Swiss pieces |
| 916, 22ct, 22K | 22ct | 91.6% | Indian, Pakistani and Middle Eastern jewellery, sovereigns |
| 999, 24ct, 24K | 24ct | 99.9% | Bars, some Asian jewellery, Maple Leaf and Britannia coins |
Older Irish pieces carry the Dublin Assay Office marks beside the number, older British ones a crown and an office symbol. Marks that mean the piece is not solid gold: GP, GEP, HGE (gold plated), RG or 1/20 12K (rolled gold, gold filled), GF. The full picture guide is on hallmarks explained.
Step 3: multiply, then check the rate is net
Weight in grams times the published rate for the carat is your figure. Two checks before you trust a competing number: is the rate per gram, not per pennyweight or per ounce, and is it net of testing and handling fees? Ours are per gram, in euro, net, on the prices page, and the price you see is the price you are paid.
| Grade | Hallmark | We pay per gram |

| 9ct gold | 375 | €33.20$36.69£27.74 |
| 14ct gold | 585 | €53.76$59.42£44.92 |
| 18ct gold | 750 | €71.45$78.97£59.70 |
| 22ct gold | 916 | €87.26$96.44£72.91 |

What the sum leaves out
The per-gram figure prices the metal and nothing else: jewellery is bought on its gold or silver content at the published rate, whatever the design, brand or condition. Stones are not metal, so they are excluded from the weight and assessed separately, quoted for or returned. Branded watches are bought by quote rather than by the gram, and bullion coins are priced on their fine gold content. Our guide to how jewellery is priced walks through the sum piece by piece.
Questions people ask
How do I work out what my gold is worth?
Weigh it in grams, find the carat from the hallmark (375 is 9ct, 585 is 14ct, 750 is 18ct, 916 is 22ct), and multiply the weight by the buyer's published net price per gram for that carat. If a buyer will not give you a per-gram figure in advance, you cannot do this sum, which is the point of publishing it.
Can I weigh gold on a kitchen scale?
For a rough figure, yes, if the scale reads in grams to one decimal place. Take off anything that is not gold: stones, steel springs in clasps, watch movements. We weigh on a calibrated scale on camera before any offer, so your kitchen estimate is a guide, not the final number.
What if my gold has no hallmark?
It is still worth exactly what its metal content is worth. We test every piece by XRF, which reads the composition without damaging it, and pay the rate for the fineness it actually is. Unmarked pieces are common on older, resized and imported jewellery.
Is a heavier chain always worth more?
Only at the same carat. A 20 g 9ct chain contains 7.5 g of gold; a 10 g 18ct chain also contains 7.5 g. Weight times fineness is what counts, which is why the calculator asks for both.
Why is your calculator figure different from an offer I got elsewhere?
Three possibilities: a different per-gram rate, a different weight (stones included or excluded, weights rounded), or fees deducted after the headline rate. Ask the other buyer for their net price per gram for your carat and compare it with ours on the same day.
