No price per gram is fixed: you must always refer to the current spot price. ## Understanding the 925 fineness (sterling silver) The number 925 corresponds to the parts per thousand of pure silver in the alloy: an item in 925 silver, known as **sterling**, contains 92.5% fine silver and 7.5% other metals (usually copper) that give it strength. It is the most widespread modern standard for jewellery and contemporary silverware. Alongside 925 there are other finenesses: 999 (near-pure silver), 835 and 800 (often older silverware). Each fineness changes the share of fine silver, and therefore the value by weight. Identifying the fineness is the first step: it is shown by a hallmark or an engraving. In France, the Minerva hallmark guarantees solid silver of an official fineness. ## The calculation formula, step by step The calculation rests on three objective figures and one commercial variable. Here is the logic: - **Total weight** of the item in grams, measured on a precise scale; - **Fine silver weight** = total weight × 0.925 for 925 silver; - **Day's price** of silver, expressed in euros per gram of fine silver; - **Buyback rate** applied by the dealer (the share of the price actually paid). The theoretical value equals the fine weight multiplied by the day's price; the amount offered then depends on the buyback rate. Because the price moves constantly, no price per gram can be announced in advance: you always refer to the price at the time of the transaction. ## Check before you sell Before any sale, separate the items that are genuinely 925 silver from silver-plated pieces, which are not bought at the silver price. Weigh together items of the same fineness, note the weight, and ask the dealer to state the price used and the net rate. Transparent weighing, a free no-obligation valuation and written proof are the markers of a reliable dealer.

Multiply the total weight in grams by 0.925. For example, a 925 silver item holds 92.5% of its weight in fine silver, the rest being the copper alloy that provides strength. Is the price per gram of 925 silver the same everywhere? The calculation base (the day's price and the 925 fineness) is identical everywhere, but the final amount varies with each dealer's buyback rate. Compare net rates rather than fixed prices per gram. ## Read also [ Guide Free silver valuation: what it is really worth ](https://meilleur-rachat-argent.fr/en/guides/free-silver-valuation/)[ Guide Selling a silver bar: channel, price, traceability ](https://meilleur-rachat-argent.fr/en/guides/sell-silver-bar/)[ Guide Selling silver: jeweller or buyback dealer? ](https://meilleur-rachat-argent.fr/en/guides/sell-silver-jeweller-or-dealer/) ## Sell at the best price near you Compare the silver buyers in your city.
