Gold, per gram, today
Waiting for the market
Fetching the live price…
This is the value of the metal, not an offer. A buyer will pay a percentage of it — see the ranges.
The tools
30 of them, all free, all running in your browser. Nothing you type is sent anywhere.
What is it worth?
Melt value at live market prices, and — the part buyer-run calculators leave out — what somebody is actually likely to hand you for it.
What size is it?
Rings, bracelets, bangles and watches. Every national scale is a convention laid over a measurement in millimetres, so these all work from the millimetres out.
Stones
Carat is a weight, not a size, and the two do not track each other. These convert between them, and cover hardness, birthstones and pearls.
The metal itself
Purity, alloys, density and the units gold is bought in — grams in one country, pennyweight in another, tola in a third.
Why this site is different
Nearly every gold calculator online is run by somebody who wants to buy your gold.
Their numbers are not wrong, exactly. They are the opening position in a negotiation you did not know you had entered. This site has nothing to sell and nobody to refer you to, so it can tell you the part they leave out: what the metal is worth, and how much less than that people actually pay.
This is a measurement site, never an appraisal.
An appraisal is a professional opinion of value, given by a qualified appraiser who has the item in front of them. Arithmetic performed on a number you typed is not that, cannot be that, and must never be dressed up as that.
Melt value and resale value are always kept apart.
They are different quantities and confusing them is the single most expensive mistake a person selling jewellery makes. Melt is what the metal weighs in money. What a buyer hands you is melt minus their margin — and if the piece has a maker, a stone or an age worth something, selling it for melt destroys that value permanently.
No buyer is recommended, ranked, rated or linked.
The moment this site earns a referral fee on a sale, every payout percentage on it becomes suspect. Typical payout ranges are published so the reader can judge an offer themselves; who they take it to is not our business.
Never tell the reader to sell, hold, or buy.
We do not know whether the ring is scrap or an heirloom, and the difference is not in the arithmetic. State what the metal contains and let the person who owns it decide.
No invented numbers, and no false precision.
Every constant on this site is either a defined unit, a published standard, or a range presented as a range. A stamp is a nominal claim about purity, not a measurement of it — where that matters, the page says so instead of quietly rounding it away.
No urgency, no scarcity, no fear.
"Gold is at an all-time high, sell now" is the house style of the industry this site exists to make legible. There is no countdown, no alert, no "act now" on any page here.
Nothing to sell you
No account, no email wall, no analytics, no affiliate links and no lead generation. The site is paid for by ads, which buys no influence over a single number on it.
The gallery
Visual references for the things that are quicker to look at than to read about.
What does 925 mean on jewellery?
Every mark you are likely to find, sorted by what it actually claims — solid metal, a plated layer, or nothing precious at all.
What are the different diamond shapes called?
Every shape drawn to scale at the same carat weight, so you can see which ones spend their weight on size and which spend it on depth.
How long is an 18 inch necklace?
Choker to opera, drawn on the same figure, with the measurement in inches and centimetres.

Jewelers Gallery is an independent reference site. It is not a jeweller, not a dealer and not a buyer, it has no connection to any business trading under a similar name, and it cannot value your jewellery — only the metal in it, from a weight and a purity you supply. For anything that might be worth more than its metal, see a qualified appraiser who is not also offering to buy it.
