Estimated value$3,262

Spot value of the metal only. A jeweller's price adds making charges and a margin, and a buyer pays below spot - so treat this as the benchmark, not the counter price.

À propos de cet outil

Live gold and silver rates, converted into the units people actually buy in. Metal is quoted per troy ounce on world markets, but almost nobody shops that way - jewellers price per gram and per tola, and by karat. This tool does those conversions with exact constants (31.1035 g per troy ounce, 11.6638 g per tola) and shows 24K down to 10K side by side, so you can see what your own piece is worth rather than the pure-gold headline number. Pick from 15 currencies, enter a weight, and get an instant valuation. Rates are cached briefly and clearly marked if the live feed is unreachable.

Comment utiliser cet outil

  1. Pick metal and currencyChoose gold or silver and one of 15 currencies. The rate is fetched live and the headline price updates immediately.
  2. Choose your puritySelect the karat that matches your item - 22K and 21K are the usual jewellery grades, 24K is pure bullion. Silver is sold unkarated, so that control switches off.
  3. Enter a weightType the weight and pick grams, tola, troy ounces or kilograms. The estimated value updates as you type.

Pourquoi l’utiliser

  • Per gram, per tola and per troy ounce at the same time, so you can compare a local quote against the world price.
  • Karat table from 24K to 10K with the exact purity used for each, not a rounded guess.
  • 15 currencies including USD, GBP, PKR and INR, converted through live FX rather than a fixed rate.
  • A weight calculator that values a real piece instead of just quoting the spot price.
  • Cached rates are labelled as cached, so you always know whether you are seeing a live number.
  • Free, instant and no signup.

Usages courants

  • Checking what a gold chain or bangle is worth before selling it.
  • Comparing a jeweller quote against the current world spot price.
  • Working out the metal value of an inherited piece by weight and karat.
  • Tracking the gold rate in your own currency rather than dollars per ounce.
  • Estimating the bullion value of coins or small bars.
  • Settling a family discussion about tola versus gram pricing.

Conseils pour de meilleurs résultats

  • Weigh the piece on a kitchen or jewellery scale in grams - that is the most accurate input.
  • If a hallmark says 916, that is 22K; 750 is 18K and 585 is 14K.
  • Stones and clasps are not gold, so subtract their weight before valuing.
  • The tola figure is the South Asian tola of 11.6638 g, which is the standard across Pakistan and India.
  • Silver moves in much larger percentage swings than gold, so re-check the rate on the day you trade.
  • A cached label means the feed was briefly unreachable - reload in a minute for a fresh quote.

Erreurs à éviter

  • Comparing a 22K item against the 24K headline rate, which overstates its value by about 8 percent.
  • Using an avoirdupois ounce (28.35 g) instead of a troy ounce (31.10 g) - metals are always troy.
  • Expecting a buyer to pay spot. Dealers buy below spot and jewellers add making charges on top.
  • Including the weight of stones, enamel or a non-gold clasp in the calculation.
  • Assuming the local rate in a shop window matches the world price - it usually includes duty and margin.

Questions fréquentes

Take the live 24K rate per gram shown above and multiply by the purity of your item. A gram of 24K is the headline number; 22K is about 91.6% of it, 18K is 75% and 14K is 58.3%. Set the weight to 1 gram and the karat to match your piece and the tool does exactly that.

World markets quote gold per troy ounce, which is 31.1035 grams - not the 28.35 g avoirdupois ounce. Divide the spot price per troy ounce by 31.1035 to get the 24K price per gram, then multiply by your karat purity. The rate shown here is already converted, so you only need to pick a karat and enter a weight.

Multiply the per-gram rate for your karat by the weight. Enter any weight in the calculator and switch the unit - grams, tola, troy ounces, pounds, kilograms, metric tonnes or US short tons are all supported, so the same answer works whether you are valuing an earring or a bullion bar.

It depends which ton you mean, and the difference is large. A metric tonne is 1,000 kg (1,000,000 grams); a US short ton is 907.185 kg. Both are in the unit list so you can price either without converting by hand. At any realistic gold price a single tonne runs into tens of millions, so treat the figure as indicative and check the timestamp on the rate.

This shows metal value at the market rate. A dealer buys below spot to cover their margin and refining, and a jeweller adds making charges on top when selling. Expect a real-world buy offer somewhere under the number here - the calculator tells you the floor you are negotiating against, not the price on the ticket.

The world price is quoted per troy ounce. We convert that to a per-gram price by dividing by 31.1034768, then multiply by 11.6638038 grams to get one tola. Those are the exact constants, so the tola figure matches what a jeweller would compute.

Karat is purity. 24K is essentially pure gold, 22K is 91.67 percent, 21K is 87.5 percent and 18K is 75 percent. The per-karat table multiplies the pure gold rate by that fraction, which is why an 18K item is worth roughly three quarters of a 24K one at the same weight.

No, and no tool can promise that. This is the spot value of the metal. A buyer pays below spot to cover their margin and refining, and a shop selling to you adds making charges on top. Treat this as the benchmark you negotiate around.

USD, GBP, EUR, CAD, AUD, JPY, CNY, PKR, INR, AED, SAR, TRY, BDT, NGN and ZAR. Non-dollar prices are converted through a live FX rate at the same moment as the metal quote.

Quotes are fetched live and cached for a few minutes so repeated visits are fast. If the upstream feed is briefly unreachable the last good value is shown and clearly labelled as cached, which is more useful than an error page.
