1. The 10-Second Math Behind the Price
Gold trades in 24 K (pure) ounces. Converting to 10 K is a simple formula:
Spot × 0.417 ÷ 31.1 g = Price per gram (10 K)
$3 314.75 × 0.417 ÷ 31.1 ≈ $44.44
Multiply that number by your item’s weight in grams to get its raw melt
value—the baseline most buyers start from.
2. What “10K” Really Means
- Composition: 10 parts gold, 14 parts alloy.
- Purity: 41.7 % (often stamped “417”).
- Durability: Harder than 14 K/18 K, popular for class rings.
- Color: Slightly paler yellow because of higher alloy content.
3. Price per Gram, Ounce & Penny-weight
| Unit | Formula | Today’s 10 K Price* |
|---|---|---|
| Gram | Spot ÷ 31.1 × 0.417 | $44.44 |
| Troy ounce | Spot × 0.417 | $1 382 |
| Penny-weight (dwt) | Spot ÷ 20 × 0.417 | $69.11 |
*Rounded to two decimals. Refresh for the latest spot price.
4. Why Today’s Quote Changes Every Few Minutes
- Spot volatility – COMEX & London trade nearly 24/7.
- Currency shifts – A weaker USD lifts the dollar gold price.
- Local premiums – Jewelers add fabrication and wholesale margins.
5. How to Work Out the Value of Your Jewelry
- Weigh the piece in grams on a digital scale.
- Verify the karat stamp (look for “10K” or “417”).
- Use the formula:
weight × 44.44 = melt value. - Subtract non-gold parts (stones, clasps) or have the buyer do a melt test.
- Get at least three offers; competitive buyers pay 85–92 % of melt.
6. Tips for Getting the Best Payout When You Sell
- Avoid mail-in “cash-for-gold” unless they guarantee > 85 % of melt.
- Bundle small items to clear minimum refinery fees.
- Time your sale—spot swings can change payouts by dollars per gram.
- Request a written quote that locks price until close of business.

clean restores shine.

value.
Bottom line: At today’s market close, 10-karat gold sits at about
