How Much Is 10k Gold Worth Per Gram Today?

By Michael Tanguma, Founder & CEO of Heirfolio. Reviewed by Diana Cruz, GIA Graduate Gemologist. Updated continuously.

TL;DR. As of today, 10k gold is worth ${{ liveSpot10kPerGram }} per gram at melt — that's the raw metal value, computed on 41.7% gold content. Most buyers pay 55-80% of that, with the rest as spread for refining, margin, and inventory risk. The number below updates every 60 seconds against the live London gold fix. Below it, the math, the wider-than-average spread on 10k, and where 10k pieces actually sell for fair money.

What this number means

The price above is the pure melt value of 10k gold per gram, computed from the live London gold fix and 10k's gold content of 41.7%. It's the number a refinery would pay if all that mattered was the metal.

10k is the lowest karat legally sold as "gold" in the United States. Because more than half the alloy is base metal, refining recovery is lower than for higher karats, and the per-gram melt value is the smallest of any common karat. That changes how buyers price it — and where you'll find the best payout.

How 10k gold pricing works

Gold purity is measured in karats out of 24. The breakdown:

Karat	Pure gold content	Common uses
24k	99.9%	Investment bars, coins, ceremonial Asian jewelry
22k	91.7%	Indian, Pakistani, Filipino, Gulf jewelry
18k	75.0%	High-end designer pieces
14k	58.5%	The American workhorse — wedding bands, chains, rings
10k	41.7%	Class rings, lower-cost jewelry, mass-market chains

To compute 10k gold's melt value per gram:

(spot price of pure gold per gram) × 0.4167 = melt value of 10k per gram

So if pure gold trades at $97.65 per gram (about $3,037 per troy ounce), 10k is worth $97.65 × 0.4167 = $40.69 per gram at melt. The live number at the top of this page runs that calculation every 60 seconds against the London fix.

For comparison: at the same spot, 14k would be $57.13/gram (40% more than 10k), and 18k would be $73.24/gram (80% more than 10k). The karat ratio scales the melt value directly.

What you'll actually get paid (the spread question)

Melt value is what your gold is worth to a refinery. What you'll be paid is melt minus a spread.

The spread on 10k tends to be wider than on higher karats because:

Refining yield is lower. Less than half the alloy is gold. The refinery's per-gram processing cost is the same regardless of karat, but the gold recovered per gram is smaller.
Per-piece value is lower, so the same dollar margin is a bigger percentage of the payout.
Buyers process lower-karat material in volume. They're optimizing for throughput, not per-piece negotiation, so they default to a wider spread to protect margin.

Typical spreads on 10k by channel:

Where you sell	Typical spread on 10k gold
Direct platform with published spread (e.g., Heirfolio)	10–18%
Mail-in gold buyer (Express Gold Cash, SellYourGold, Gold Guys)	18–35%
Local jeweler buying for melt	25–40%
Local jeweler buying for resale	15–30% (rare on 10k)
Pawn shop	45–70%

If the melt value of a 10k chain is $40.69 per gram and the chain weighs 15 grams:

15 grams × $40.69/gram = $610.35 raw melt value

Channel	What you'd actually be paid
Heirfolio (13% spread)	~$531
Mail-in buyer (25% spread)	~$458
Local jeweler for melt (32% spread)	~$415
Pawn shop (55% spread)	~$275

That's a $256 difference between the best and worst legitimate channel for the same chain — proportionally even larger than the gap on 14k or 18k. For 10k specifically, the channel choice is the single biggest factor in what you'll receive.

The class ring economy

A large share of inherited 10k pieces are class rings — high school or college rings produced by Jostens, Herff Jones, ArtCarved, and similar manufacturers. These rings are almost always 10k (occasionally 14k for premium upgrades), weigh 8–15 grams, and have stones that are usually synthetic.

A few things to know:

The synthetic stones have no resale value. A class ring's gold weight is the entire value at melt.
The class ring "buyback" programs advertised by some companies typically pay 30–50% of melt — well below fair. They're betting on emotional fatigue, not market price.
Engraving doesn't reduce melt value. The buyer is melting the piece anyway.
Box and papers don't add value for class rings the way they do for designer 18k pieces.

For a typical 10g class ring at today's spot:

10 grams × $40.69/gram = $406.90 raw melt value
Payout at 75% (decent mail-in buyer) = ~$305
Payout at 50% (Jostens-style buyback) = ~$203
Payout at 30% (pawn shop) = ~$122

Take the time to get two real quotes from independent buyers. The difference is often the cost of a meaningful gift to the grandchild who'd otherwise inherit a drawer ring.

How to verify your gold is really 10k

Pieces that look like 10k aren't always 10k — and pieces stamped as 10k aren't always actually 10k either. Five tests:

1. Look for the hallmark

Genuine 10k is stamped: 10K, 417, .417, 10KT, 10kt, or sometimes 10 K. The stamp will be on a clasp, the inside of a ring band, or the back of a pendant. No stamp doesn't always mean fake — some older pieces aren't marked — but it raises the question.

2. Magnet test (free, 30 seconds)

Gold isn't magnetic. A magnet that sticks rules out solid gold. 10k has the highest base-metal content of any gold karat, so it's especially worth running this test — plated steel pieces often look like solid 10k.

3. Acid test ($15 home kit)

Apply the 10k acid to a tiny scratch in an inconspicuous spot. If the scratch fades quickly, the piece is below 10k or not gold. If it holds, it's 10k or higher.

4. Electronic gold tester ($60–200)

Reads electrical conductivity. Reliable for plain pieces; less reliable for layered construction.

5. XRF testing (professional)

X-ray fluorescence reads the exact composition non-destructively. Most jewelers do it for free if you're considering selling. Heirfolio runs XRF on every piece received.

Common 10k piece weights

Real-world weights to anchor the math:

Piece type	Typical weight in 10k	Melt value at today's spot
Class ring (high school or college)	8–15 grams	${{ class_ring_melt }}
Men's wedding band (6mm, plain)	5–9 grams	${{ wedding_band_melt }}
Women's wedding band (2mm, plain)	1.5–3 grams	${{ wb_women_melt }}
Thin 10k chain (18 inches)	3–6 grams	${{ chain_thin_melt }}
Heavy 10k Cuban link (22 inches)	30–80 grams	${{ chain_heavy_melt }}
Charm or pendant	1–4 grams	${{ pendant_melt }}
Pair of stud earrings	1–3 grams	${{ earrings_melt }}
10k school sports ring (championship)	12–25 grams	${{ sports_ring_melt }}

These are melt values. Subtract 15–35% for a typical buyer spread on 10k. The gold melt value calculator computes both.

Should you melt a 10k piece or sell it whole?

For 10k specifically, the answer leans toward melt — but not always.

Sell for melt if:

The piece is plain, generic, and not branded.
The piece is broken, mangled, or unrepairable.
The piece is a class ring with synthetic stones and no special history.
The piece is a mass-market chain or band with no design value.

Consider selling whole if:

The piece is from a recognized designer who works in 10k (rare — most designers use 14k+).
The piece has stones of meaningful value (real diamonds, sapphires, rubies). Sell the stones separately and the metal separately.
The piece has historical or sentimental value that a niche buyer might pay for (a vintage 10k Masonic ring, an antique 10k locket, an early-1900s 10k gold pocket watch case).
The piece has unusual character — Art Deco styling, hand-engraved details, named maker — that lifts it above generic.

Mail-in gold buyers almost always melt 10k. A direct platform like Heirfolio evaluates both paths and chooses the higher payout.

Why 10k specifically?

A note on why 10k exists and what that means for resale.

10k is the lowest karat that U.S. law allows to be sold as "gold" (the federal minimum is 10k = 41.6% gold; below that, the piece must be sold as "gold alloy" or another descriptor). The karat exists because of price sensitivity in the mass-market segment — class rings, costume-adjacent fine jewelry, lower-cost wedding bands. The added base metal makes the piece cheaper to produce and harder than 14k, which extends its life under daily wear.

The practical implications for resale:

The international market for 10k is thin. Outside the U.S. and Canada, almost no fine jewelry is made in 10k. A 10k piece sells primarily in North America.
Melt is the dominant exit. Most 10k pieces are melted because the design market for 10k is small.
Brand premium on 10k is rare. A 10k Tiffany piece exists (some men's bands), but it's the exception. Most designer houses won't go below 14k.
Older pieces (pre-1980s) sometimes assay slightly above 10k because manufacturing tolerances weren't tight. A piece stamped 10k that assays at 12k pays more — always test before assuming the stamp.

What changes the price you see on this page

The number at the top updates every 60 seconds. Spot moves because:

Macroeconomic conditions — inflation expectations, real interest rates, U.S. dollar strength.
Geopolitical events — gold rises during uncertainty.
Central bank buying — when the Fed, ECB, China's PBOC, India's RBI, or Turkey's central bank moves, the market moves.
Industrial demand — gold is used in electronics.
ETF flows — the major gold ETFs hold real gold. Inflows push spot up.

For 10k specifically, the channel decision (which buyer) usually matters more than the timing decision (which week). Spreads on 10k vary by 20–40 percentage points across channels; spot rarely moves more than 3–5% in a typical week.

Frequently asked questions

How much is 10k gold worth per gram today?

As of the latest London gold fix, 10k gold is worth ${{ liveSpot10kPerGram }} per gram at melt. That's the raw metal value, computed on 41.7% gold content. Buyers typically pay 55–80% of that, with the rest as spread. The number on this page updates every 60 seconds.

Is 10k real gold?

Yes. 10k contains 41.7% pure gold by weight, alloyed with copper, silver, zinc, or nickel. It's the lowest karat that U.S. law allows to be sold as "gold." It's genuine gold, recognized by every refinery and dealer — just less of it per gram than higher karats. Pieces stamped 10K, 417, or 10KT are 10k gold. Pieces stamped GF (gold-filled), GP (gold-plated), or RGP (rolled gold plate) are not solid 10k.

How does 10k compare to 14k or 18k?

The number indicates how much pure gold is in the alloy out of 24 parts. 10k is 41.7% pure gold, 14k is 58.5%, 18k is 75%. So 14k has 40% more gold per gram than 10k, and 18k has 80% more. Melt value per gram tracks that ratio directly. 10k is harder than higher karats (more base metal), which makes it good for daily wear but less valuable as metal.

Why is the spread on 10k wider than on 14k or 18k?

Three reasons. Refining yield is lower because more than half the alloy is base metal. Per-piece dollar value is lower, so buyers protect margin with a wider percentage spread. And the design-market exit is rare on 10k, so almost everything goes to melt — buyers price for the throughput business, not for any per-piece negotiation.

What's a class ring actually worth at melt?

Most class rings weigh 8–15 grams in 10k. At today's spot, that's ${{ class_ring_melt_low }}–${{ class_ring_melt_high }} in raw melt value. After a typical 20–30% spread at a reputable mail-in buyer, expect ${{ class_ring_payout_low }}–${{ class_ring_payout_high }} in actual payout. The synthetic stones have no value. The engraving doesn't matter (the piece is melted). Jostens and Herff Jones buyback programs typically pay 30–50% of melt — well below fair.

How do I verify my 10k gold is real?

The fastest free test is a magnet — gold isn't magnetic. A $15 acid testing kit from Amazon tells you the karat reliably. The most accurate test is X-ray fluorescence (XRF), which most jewelers do for free if you're considering selling. 10k has the highest base-metal content of any gold karat, so it's especially worth running the magnet test — plated steel often impersonates 10k.

Where is the best place to sell 10k gold?

For plain 10k chains, bands, or scrap, a direct platform with a published spread (like Heirfolio) or a reputable mail-in buyer (Express Gold Cash, SellYourGold) pays closest to melt. For class rings, the same path applies — avoid the manufacturer buyback programs, which pay below market. For pieces with real stones, sell stones separately. Avoid pawn shops on 10k specifically — they often pay 45–70% below melt.

What's the typical spread on 10k gold?

Direct platforms with published spreads charge 10–18%. Mail-in gold buyers charge 18–35%. Local jewelers buying for melt charge 25–40%. Pawn shops charge 45–70%. To check any quote: divide the offer by (weight in grams × today's 10k melt value per gram). The result is what percent of melt you're being offered. Anything under 65% on 10k is below industry-fair for a private seller.

Should I clean my 10k gold before selling?

For melt sales: no. The buyer is going to melt it anyway, and aggressive cleaning can scratch the piece without helping anyone. For resale of an unusual piece (vintage, hand-engraved, designer): yes, gently. Soft toothbrush, warm water, drop of dish soap. Don't use silver polish or ultrasonic cleaners on pieces with stones — settings can loosen.

Why does my 10k piece weigh less than I expected?

A few possibilities. Hollow construction is common in chains and hoops — the piece looks bulky but is light. Stones don't count toward gold weight. Some 10k pieces are constructed with non-gold internal components. And if the piece is plated, gold-filled, or vermeil rather than solid 10k, the gold weight is a fraction of the total weight. Always verify the hallmark and run a test before assuming solid 10k.
