10K scrap gold calculator

Identify 10K before weighing

10K gold contains 41.67% gold and is the minimum karat that can legally be sold as "gold" in the United States. It is pale yellow and very durable. The stamps are 417, 10K or 10KT. Because 10K contains more alloy, it may tarnish slightly over time — this is normal and does not mean it is fake. Read the complete stamp: a plated or filled qualifier means the full weight cannot be valued as a solid 10K 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

10K is widely used for budget jewellery, class rings, and men's chains in North America, where its hardness and lower price per gram make it practical for daily wear. 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 10K to everything. Record the scale unit and its precision; grams and pennyweights are not interchangeable.

How this 10K calculator works

The nominal factor is 0.4167, so each net gram contains about 41.67% gold. We divide the fine-gold spot ounce by 31.1034768, multiply by your weight and then by this factor. A common 417 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. Because 10K has less gold per gram, scrap offers are lower than for 14K. Use the calculator to convert your weight to pure gold before comparing buyer quotes. 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 10K 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.
