14K Gold Price Per Gram: Estimating Jewelry Value
Estimate 14K gold content using net alloy weight × 14/24, then multiply by the pure-gold price per gram. The result is a metal-content estimate, not a purchase offer.
Calculate the gold content before comparing prices
To estimate the metal value of 14K gold, multiply the pure-gold price per gram by 14 ÷ 24, or approximately 0.5833. Then multiply by the net weight of the 14K alloy. This estimates contained gold value; a purchase offer also depends on the actual item and the buyer's terms.
14K means 14 parts gold in a 24-part alloy. A 585 fineness mark indicates 58.5% gold and is commonly associated with 14K jewelry. The World Gold Council's explanation of karat and fineness describes the small distinction between nominal 14K and 585. Use the purity established during the evaluation when comparing a real offer. Our guide to 14K marks, color and construction explains what these descriptions tell you.
A marking is a starting clue: stamps can wear, repairs can introduce other metals, and separate components may have different purities. Ask how purity will be checked and whether a proposed test could mark the piece. GIA’s 1992 study of gold-testing methods provides historical background on touchstone, electronic and X-ray fluorescence (XRF) testing and their limitations.
Convert a troy-ounce reference into grams
If a gold-price reference is quoted in dollars per troy ounce, first divide it by 31.1034768 to obtain dollars per gram of pure gold. A troy ounce is different from an ordinary household ounce. The NIST mass reference provides the conversion.
Estimated contained gold value = net alloy weight in grams × tested gold fraction × pure-gold price per gram.
The World Gold Council's gold-price data offers market references. Check the currency, unit, date, and whether a displayed value is an average or benchmark. It is not a binding offer for your jewelry, and this article does not display a live buying rate.
Worked example: a 25-gram 14K bracelet
Assume a plain bracelet contains 25 grams of 14K alloy after accounting for any non-gold components. Its estimated pure-gold content is 25 × 14 ÷ 24 = approximately 14.58 grams. Multiply that amount by the current reference price per gram of pure gold to obtain a metal-content estimate.
| Net 14K alloy weight | Approximate pure gold |
|---|---|
| 10 grams | 5.83 grams |
| 25 grams | 14.58 grams |
| 100 grams | 58.33 grams |
These are calculated metal quantities, not promised payouts. A bracelet's total weight may also include diamonds, non-gold springs, or other materials. A household scale and a visible stamp can help you prepare questions, but they do not establish a tested net gold weight.
Understand the difference between a reference and an offer
A metal-only purchase offer can reflect testing, processing, refining, resale costs, and the buyer's margin. Jewelry with a desirable maker, significant stones, or collectible features may instead deserve evaluation as a complete piece. Do not add an intact jewelry resale estimate to its full metal value; that could count the same material twice. To distinguish a retail receipt or replacement appraisal from a current offer, read what to expect for gold jewelry.
For heavy Cuban chains and bracelets, ask about construction as well as weight. Hollow links and solid links can look similar while containing different amounts of metal. If diamonds are present, ask how the stones affect both the weight calculation and the offer. See our 14K chain guide for these item-specific checks.
Compare 14K gold offers on the same basis
Keep the same pieces together when requesting comparisons. Ask each buyer to state the tested purity, weight unit, weight used, whether stones are included, any charges, and the final payment. If one quote uses grams and another uses pennyweights, ask for matching units before comparing rates. Use the gold-offer comparison worksheet to record the same details for each buyer.
An estimate given before examination may change if the item differs from the description. Compare final amounts for the actual jewelry, not only an advertised per-gram figure. Our gold-valuation guide covers the broader factors behind an offer.

Are equal weights of 14K white, yellow and rose gold worth the same?
At the same tested gold fraction, they contain the same amount of gold. A complete piece's offer may still differ because of its stones, maker, condition, or resale demand. Read more about white gold's alloy and finish.
Should I remove stones before weighing my jewelry?
No. Have the intact jewelry evaluated first and ask how non-gold weight is accounted for. Removing stones can damage the setting and make an evaluation of the complete piece more difficult.
Can this formula tell me the best day to sell?
No. It explains metal content using a stated price reference; it does not predict markets. Decide using an actual offer, the items you own, and your circumstances.
