How Much Is My Gold Jewelry Worth? 10K–24K Gold Value Guide

How much is my gold jewelry worth? The short answer: it depends on today's gold spot price, the weight of your piece, its karat (purity), and — for some jewelry — added value from gemstones, brand, or collectibility. The metal value follows a simple formula you can calculate yourself in under a minute.

This guide explains exactly how gold jewelry value is calculated, gives you a live calculator to estimate your own, shows real examples for 10K, 14K, 18K, 22K, and 24K pieces, and breaks down why two buyers can offer very different amounts for the same jewelry. By the end, you'll know how to estimate your gold's worth — and how to make sure you actually receive it.

How Gold Jewelry Value Is Calculated

Gold jewelry value comes from one straightforward formula. Once you understand it, you can estimate almost any piece yourself:

Weight is how much your piece weighs in grams (gold is priced per troy ounce, which is 31.1 grams). Purity is the percentage of actual gold in the alloy — a 14K piece is 58.5% gold. Current pure-gold value is today's spot price converted to a per-gram figure. Multiply the three together and you get the melt value — the metal content of your piece.

That melt value is the floor. A buyer's cash offer is usually a percentage of it, and certain pieces are worth more than melt because of brand, craftsmanship, or stones. We'll cover all of that below — but first, the karat system that drives the purity number.

Karat Purity at a Glance

Karat (K) measures how much pure gold an alloy contains. Here's every common karat, its gold content, and the stamp you'll usually see on the piece:

How Much Is Gold Worth Per Gram?

The spot price of gold is quoted per troy ounce (31.1 grams). To get the value of pure gold per gram, divide the spot price by 31.1. Then multiply by the karat purity to get the per-gram melt value of a specific alloy. This is the single most useful number to know when estimating your own jewelry.

For example, if pure gold trades at $3,000 per troy ounce, pure gold is worth about $96.46 per gram. From there:

• 24K (99.9%) ≈ $96.37/g
• 22K (91.6%) ≈ $88.36/g
• 18K (75.0%) ≈ $72.35/g
• 14K (58.5%) ≈ $56.43/g
• 10K (41.7%) ≈ $40.23/g

The gold price per gram moves every business day as global markets trade. That's why a calculator tied to a live price — rather than a static number printed months ago — gives you a far more accurate estimate.

Enter your jewelry's weight and karat below. The calculator pulls today's live gold spot price and shows your estimated melt value instantly. It's the same data our full gold value calculator uses.

Remember: the calculator shows the melt value — the pure metal content of your piece. A real cash offer is a percentage of that, and certain pieces are worth more than melt. The sections below explain both.

Real Examples: How Much Common Gold Jewelry Is Worth

Here are three real-world examples using the formula above at a $3,000/oz spot price. The logic is identical for any piece — only the weight, karat, and live price change.

How Much Is Your Gold Worth by Jewelry Type

Per gram, a karat is a karat — 14K gold is worth the same whether it's in a ring or a chain. What changes between jewelry types is typical weight and whether the piece might carry added resale value.

How Much Is a Gold Ring Worth?

A standard 14K wedding band weighs about 4–7 grams — roughly $225–$395 in melt value at a $3,000/oz spot. A heavy men's signet can run 15–25 grams. The biggest variable beyond weight is whether the ring holds a diamond or center stone, which is valued separately and can dwarf the gold itself.

How Much Is a Gold Chain Worth?

Chains vary enormously in weight. A dainty 14K chain might weigh 5 grams; a solid Cuban Link chain can weigh 50–100 grams. Watch for hollow vs. solid chains — a hollow chain looks large but weighs far less than it appears, which is the most common reason a seller is surprised by a lower number.

How Much Is a Gold Bracelet Worth?

Bracelets tend to be heavier than rings and chains of similar visual size. A 14K gold bracelet often lands in the 20–60 gram range. Designer bracelets (Cartier, Tiffany, David Yurman) can carry a resale premium well above melt — see the melt-vs-resale section below.

How Much Are Gold Earrings Worth?

Most gold earrings are light — often 1–4 grams per pair — so their metal value is modest. A single lost earring is still worth its full per-gram value, which is why buyers accept "incomplete" pairs happily. Stone-set earrings are valued for both metal and stones.

How Much Is Broken Gold Jewelry Worth?

Broken, bent, or tangled gold is worth exactly the same per gram as intact gold — because value comes from metal content, not condition. A snapped scrap gold chain, a single earring, a ring missing a stone, or a kinked bracelet all retain full melt value. Never throw broken gold away; it's one of the most common ways people accidentally discard real money.

Melt Value vs. Resale Value

This distinction matters more than any other on this page. Melt value is what the raw metal is worth. Resale value is what a piece is worth as jewelry — and for the right pieces, resale value can be much higher.

A buyer who only weighs your piece and pays melt value is treating every item as scrap. That's fine for a tangled chain or a plain band — but it's the wrong approach for jewelry that has value beyond its metal:

• Recognizable luxury brands — a signed Cartier, Tiffany & Co., or Van Cleef & Arpels piece can sell for a premium above melt to a buyer who can resell it as designer jewelry.
• Craftsmanship & design — finely made or intricate pieces have labor and design value that scrap pricing ignores.
• Antique & vintage appeal — older pieces from desirable eras can carry collectible value.
• Natural diamonds & gemstones — stones are valued on their own merits (see the next section).

Diamonds & Gemstones Change the Math

Stones are not gold, and they should never be valued as gold weight. A diamond-set ring has two separate values: the gold (by weight and karat) and the stone (by its own grading). Treating a ring with a one-carat diamond as "just gold" means a buyer is quietly keeping the stone's value for free.

• Natural diamonds — valued by the 4Cs (carat, cut, color, clarity). A well-graded natural stone can add substantial value.
• Lab-grown diamonds — chemically identical to natural diamonds but far less expensive per carat; still worth something, but much less than natural.
• Colored gemstones — sapphires, rubies, emeralds, and others vary enormously; only a gemologist can give a reliable estimate.
• Small melee stones — the tiny accent diamonds in many settings add relatively little individually, but can add up.
• Large center stones — these drive most of a stone-set piece's value and must always be appraised separately from the gold.

What If the Jewelry Has No Karat Stamp?

Plenty of genuine gold has no visible stamp. Older pieces, resized rings (the stamp gets cut during sizing), and much imported jewelry arrive unmarked. A missing stamp does not mean a piece isn't gold.

It also works the other way: a stamp alone doesn't prove purity. Counterfeits carry forged 14K and 18K stamps, and wear can obscure a real mark. Reasons a stamp can be misleading:

• A stamp can wear off or be removed during repair or resizing.
• European pieces use millesimal fineness numbers (585, 750) instead of K stamps.
• Plated jewelry sometimes carries a confusing "14K" or "18K" mark referring to the plating, not solid content.
• A forged stamp on a non-gold base metal is common on counterfeits.

The only way to know a piece's true purity is professional testing — which brings us to how that actually works.

How Professional Gold Testing Works

There are five common ways gold is tested. Each tells you something different, and the method a buyer uses can quietly affect your payout — especially on borderline karats where a misread can cost you 25% or more.

Why Two Gold Buyers Can Offer Very Different Amounts

Here is the most important consumer insight on this page: the underlying gold spot price is the same for every buyer — it's a global public market. So why do offers for the same piece vary so much? Because each buyer applies a different percentage of your item's actual value, and for different reasons:

• Buyer margins — a pawn shop that needs to resell quickly takes a larger cut than a specialist who refines or resells directly.
• Testing methods — a buyer using acid testing may conservatively round a borderline karat down; XRF reads the true alloy.
• Hidden fees — some buyers quote a price and then deduct "testing," "handling," or "refining" fees after the fact.
• Resale potential — a buyer who can resell a designer piece as jewelry can pay more than one who only sells it for melt.
• Refining relationships — buyers who send volume to a refinery get better rates and can pass more to you.
• Operating costs — a high-overhead storefront needs a bigger margin than a lean mobile operation.
• How stones & brand are valued — a buyer who ignores your diamond pays only for gold; one who appraises it pays more.
