Live melt value for 10K gold — 41.67% pure gold (417, 10K, 10KT, 10ct)
10K gold contains exactly 10 parts gold per 24 — 41.67% pure gold, with the remaining 58.33% composed of silver, copper, zinc, nickel, or palladium depending on the color variant. It is the most affordable solid gold option and the dominant karat in US budget and fashion jewelry, class rings, and children's jewelry.
Critically, 10K is the legal minimum karat to be sold as "gold" in the United States. Under the National Stamping Act (15 U.S.C. §294–300) and FTC regulations (16 CFR Part 23), any item below 10K purity cannot use the word "gold" in its labeling or description — it must be called gold-filled, gold-plated, or omit gold entirely. This is a federal statute with civil and criminal penalties for misrepresentation. The UK and Australian legal minimum is 9K (37.5%, stamped 375). Most European nations recognize 9K, 14K, and 18K as standard hallmark finenesses — 10K is not a recognized standard in EU hallmarking systems, which limits its international resale liquidity compared to 14K or 18K.
| Weight | Pure Gold Content | At $3,000/oz | At $3,200/oz |
|---|---|---|---|
| 1 gram | 0.4167 g | $40.19 | $42.87 |
| 1 DWT (pennyweight) | 0.648 g | $62.50 | $66.67 |
| 5 grams | 2.084 g | $200.96 | $214.36 |
| 10 grams | 4.167 g | $401.92 | $428.72 |
| 1 troy oz (31.1g) | 0.4167 ozt | $1,250.10 | $1,333.44 |
| 1 oz avoirdupois (28.35g) | 0.3799 ozt | $1,139.66 | $1,215.64 |
All three color variants contain 41.67% gold. Only the alloying metals — and therefore the color, hardness, and allergen profile — differ:
| Color | Gold | Silver | Copper | Other | Notes |
|---|---|---|---|---|---|
| Yellow | 41.67% | ~52% | ~6.33% | — | Slightly pale yellow vs. 18K; silver dominates the alloy |
| Rose | 41.67% | ~20% | ~38.33% | — | High copper content creates warm pink-to-rose hue |
| White | 41.67% | — | — | Ni+Zn or Pd | Nickel-based whitening is common at this purity; allergy risk — see below |
Melt value is identical for all three colors — refiners purchase only the gold fraction at spot. The alloy metals (silver, copper) are recovered separately at their own market rates, but the buyer's offered price is based purely on gold content.
10K white gold carries a meaningfully higher nickel allergy risk than 14K or 18K white gold. The reason is economic: palladium is the premium whitening agent for white gold alloys — it produces a cleaner white and is hypoallergenic — but palladium is expensive. At 10K purity, where the gold fraction is already low, using palladium as the whitening agent significantly raises the alloy cost. Nickel is the cheaper alternative and is common in 10K white gold.
Nickel contact dermatitis affects approximately 10–15% of women and 1–2% of men, causing redness, itching, and blistering at jewelry contact points. The European Union restricts nickel release in jewelry under REACH Regulation EC 1907/2006 — items releasing more than 0.5 μg/cm²/week cannot be sold as jewelry in the EU. The US has no equivalent federal restriction. If you have a known nickel sensitivity, ask your jeweler to confirm whether the 10K white gold piece uses a nickel-based or palladium-based alloy before purchasing. Rhodium plating (applied to most white gold jewelry) provides a temporary barrier but wears off over 12–18 months with typical wear.
Standard stamps for 10K gold: 417 (millesimal fineness — 41.7 parts per hundred), 10K, 10KT, 10ct. Note: "417" rounds up slightly from the exact figure of 41.666...% — this rounding is permitted under FTC conventions. Stamps with letter suffixes after the karat number are not solid gold: 10K GF = gold-filled; 10K GP = gold-plated; 10K RGP = rolled gold plate.
Stamp locations: inner ring band, chain clasp, bracelet safety clasp, pendant bail or reverse face, earring post or back. If no stamp is present, ask for XRF (X-ray fluorescence) testing before selling — it's non-destructive and takes seconds.

Live melt value is shown in the calculator above, updated every 60 seconds. Formula: spot price ÷ 31.1035 × 0.4167. At $3,200/oz: $42.87/gram. At $3,000/oz: $40.19/gram. At $2,800/oz: $37.52/gram. Multiply by your weight in grams for total melt value.
Yes. Under the National Stamping Act (15 U.S.C. §294–300) and FTC regulations (16 CFR Part 23), 10K is the minimum karat that can legally be described or sold as "gold" in the United States. Items below 10K cannot use the word gold in their labeling. This is a federal law with civil and criminal penalties. The UK and Australian minimum is 9K (37.5%). Most EU countries don't recognize 10K as a standard hallmark fineness at all — 10K gold has limited international resale liquidity compared to 14K or 18K.
All three indicate 10K gold (41.67% pure). "417" is the millesimal fineness mark — 417 parts per 1,000, which rounds up from the exact figure of 41.666...% (FTC allows this convention). "10K" and "10KT" (T = troy) are the US karat stamps. Watch for letter suffixes: "10K GF" = gold-filled (not solid gold); "10K GP" = gold-plated; "10K RGP" = rolled gold plate. A bare "10K" or "417" with no suffix = solid gold.
Yes — meaningfully so. White gold requires a whitening alloy metal. Palladium is hypoallergenic and produces the cleanest white, but it's expensive. At 10K purity, palladium adds significant cost to an already budget-oriented product, so nickel is frequently used instead. Nickel contact dermatitis affects ~10–15% of women. The EU restricts nickel release in jewelry under REACH Regulation EC 1907/2006; the US has no equivalent. If you have nickel sensitivity, confirm the alloy composition before buying 10K white gold, or choose 14K/18K white gold where palladium is more cost-viable. All white gold is rhodium-plated, but that wears off in 12–18 months.
All contain 41.67% gold — only the alloying metals differ. 10K yellow: ~41.67% Au + ~52% Ag + ~6.33% Cu. The high silver content gives 10K yellow gold a slightly cooler, paler yellow than 18K. 10K rose: ~41.67% Au + ~20% Ag + ~38.33% Cu. High copper content creates the warm pink hue. 10K white: ~41.67% Au + nickel/zinc or palladium blend to bleach color. Melt value is identical for all three colors — refiners pay only for the gold fraction.
Typical payout as % of melt: direct refiners 90–95%; online gold buyers 88–93%; local coin dealers 85–92%; jewelry stores 70–85%; pawn shops 50–70%. Calculate your melt value above first, then divide any offer by it. Example: "$18/gram" at $3,200/oz spot (melt = $42.87/gram) = 42% of melt — pawn shop territory. Get at least two quotes, and note that 10K has lower international recognition than 14K or 18K, which can affect refiner margins slightly.
