Identify 21K before weighing
21K gold is 87.5% pure and is especially popular in Egypt, Saudi Arabia, the UAE and other Middle Eastern countries, where it is the most traded grade in gold souks. Look for 875 or 21K. In Gulf countries items are often hallmarked with the national assay mark alongside 21. Read the complete stamp: a plated or filled qualifier means the full weight cannot be valued as a solid 21K alloy. A worn mark is not a laboratory result. If the construction is unclear, ask for appropriate professional testing before relying on a calculation.
Use net metal weight, not the whole object
It offers a strong yellow colour with more hardness than 22K, so it is used for everyday bracelets, rings and chains. Many Middle Eastern gold shops quote a daily 21K price per gram on their boards. Stones, watch movements and unrelated steel parts contribute gross weight without adding the same gold content. Keep each purity in a separate group. If you have a mixed lot, use the main scrap calculator to add individual lines instead of applying 21K to everything. Record the scale unit and its precision; grams and pennyweights are not interchangeable.
How this 21K calculator works
The nominal factor is 0.875, so each net gram contains about 87.50% gold. We divide the fine-gold spot ounce by 31.1034768, multiply by your weight and then by this factor. A common 875 stamp and an exact karat fraction can differ slightly; for a binding settlement, an accepted assay is more precise. The default payout is 100%, which displays metal reference rather than predicting a buyer's offer.
Compare offers without guessing a standard percentage
Change the payout field to a percentage you are considering. It is your assumption, not a rate measured from dealers. Request the final net payment, accepted grams, tested purity and all fees from the buyer. Gulf jewellers publish daily buy and sell prices for 21K. Compare their buy price with the per-gram melt value on this page to see the dealer's margin. Jewelry with a desirable maker or intact stones may be better sold second-hand, so investigate that route before authorizing melting or destructive testing.
Practical checks for a 21K sale
Photograph the marks and item, weigh it with suitable precision and keep purchase or inheritance records where available. Compare written offers made at a similar quote time. A pawn loan is not a sale: its interest, redemption charges and deadline need separate assessment. Taxes depend on location and circumstances; the reference is not a tax-inclusive retail price or financial advice. Live responses are cached for five minutes, and the timestamp—not the page refresh—is the freshness check.
