Most U.S. scrap bags lean hard on 10K. People still talk like every yellow piece is "gold," then get quiet when the buyer starts at forty-one-point-seven percent.
That silence costs money both ways. You walk in hoping for 14K math; they pay 10K rates. Or you shrug off a heavy 10K lot as junk and leave real metal on the table.
This calculator locks purity near 41.7% (hallmark 417) so weight and spot finally match what 10 karat means at the counter.
What 10K actually pays for
You're selling the fine gold inside the alloy — not the stamp romance. Ten parts in twenty-four. Roughly 4.17 g of pure gold in every 10 g of solid 10K.
Buyers know that. Their posted "10K price" already builds in testing, refining, and margin. Your job is to know the melt-style ceiling before you nod at a ticket.
Solid 10K / 417 only. GF, plate, or fuzzy marks belong on a different path.
Steps before you hit calculate
- Read every clasp, shank, and tag for 10K or 417.
- Pull out 14K, 18K, and filled pieces — one wrong piece skews the bag.
- Weigh dry metal. Note stones and steel findings you can't pull.
- Match the scale unit: grams, DWT, or troy ounces — don't switch mid-math.
- Compare the result to the offer. Cash often sits under full melt after assay.
10K vs the "half of spot" habit
Some counters still quote 10K like it's "about half." Half of spot understates 0.417 math when they're talking pure-gold equivalents — and overstates it when they casually apply half to jewelry weight without saying so.
Ask which sentence they mean: dollars per gram of jewelry, or dollars per gram of fine gold. Those phrases sound identical across glass. They aren't.
For stamp context across karats, keep the gold purity hallmark chart open. Numbers like 417 vs 585 stop a lot of arguments early.
Quick 10K reference
| Measure | Figure |
|---|---|
| Karat | 10K |
| Purity | ≈ 41.7% (10 ÷ 24) |
| Common mark | 417 |
| Pure gold in 10 g of 10K | ≈ 4.17 g |
| Pure gold in 10 DWT of 10K | ≈ 4.17 DWT fine basis |
Formula: value ≈ weight × 0.417 × gold price on the same unit basis.
EXAMPLE — 20 g chain at illustrative spot
EXAMPLE spot: $4,000 / troy oz (illustrative only — not a live quote).
Pure gram price ≈ 4000 ÷ 31.1035 ≈ $128.60 / g.
Solid 10K chain, 20 g, stones out:
Fine gold ≈ 20 × 0.417 = 8.34 g
Melt-style ≈ 8.34 × 128.60 ≈ $1,072.
Run the same weight at 14K purity (0.583) by mistake and you invent roughly 40% more value that isn't there. Lock 10K first.
Sorting tricks that save a ticket
Heavy stone clusters hurt 10K worse than higher karat — less fine gold per gram of scale weight. Pull what you can.
Broken 10K fragments almost always track scrap. Clean wearable bands sometimes clear a jewelry offer above melt. Don't force one path on both.
If the number surprises you, change one input: purity, weight, or spot. Guessing three things at once just moves the fiction around.

Frequently Asked Questions
How much pure gold is in 10K?
About 41.7% of the alloy weight (10 ÷ 24). Ten grams of solid 10K hold roughly 4.17 g of pure gold before stones or hardware.
Is 10K worth selling as scrap?
Often yes in sizeable lots. Per gram it returns less than 14K or 18K. Run the number, then stack offers against that melt-style line.
What does 417 mean on jewelry?
417 marks ≈ 41.7% gold — standard for 10K. Confirm the piece is solid, not filled or plated.
Why is the cash offer under my estimate?
Testing, refining, and dealer margin pull cash below full melt. Fuzzy stamps widen the gap. Ask which purity they used on the ticket.
Can 10K jewelry beat melt?
Wearable designs sometimes resell above scrap. Broken chains and odd earrings usually don't. Match the path to condition.
Does this work in pennyweight?
Yes. Enter DWT if the tool allows, or convert with 1 DWT ≈ 1.55517 g. Keep purity at 0.417 either way. More unit detail: pennyweight vs grams vs troy ounce.
