Gold Karat Chart: What 10K, 14K, 18K and 24K Gold Are Actually Worth

A gold karat chart is the single most useful tool you can have before you buy, sell, or evaluate gold jewelry. Whether you're standing at a pawn shop counter, browsing an estate sale, or comparing pieces online, knowing the difference between a 10K gold ring and an 18K one — and what that difference actually means in dollars — is the edge that separates informed buyers from the ones who consistently overpay or leave money on the table.

In 15 years of buying and selling gold through pawn shops, I've watched thousands of people make avoidable mistakes because they didn't understand the gold karat chart. They'd pay retail prices for 10K gold. They'd sell 18K pieces for the same per-gram price as 14K. Or they'd pass on a genuine deal because they didn't recognize the karat stamp.

This guide fixes all of that. We'll walk through every major karat grade — 10K, 14K, 18K, and 24K — and give you a complete gold karat chart you can bookmark and use every single time. We'll also break down the real-world comparison of 10K vs 14K gold value so you know exactly when each grade makes sense to buy, sell, or avoid.

A gold karat chart comparing the four most common karat grades by purity percentage and melt value per gram.

What Is a Gold Karat Chart and Why Does It Matter?

The word "karat" (abbreviated K or kt) refers to the proportion of pure gold in an alloy. Pure gold is 24 karats. Every other karat grade is a fraction of that — and a gold karat chart translates those fractions into practical numbers you can use when buying or selling.

Gold is never 100% gold in jewelry form. Pure 24K gold is too soft for most wearable pieces, so it's mixed with metals like silver, copper, zinc, and palladium to create alloys that are harder, more durable, and in some cases more vibrant in color. The karat number tells you exactly how much of the resulting alloy is actual gold.

Here's why the gold karat chart matters for real buyers:

• Melt value is calculated from karat purity. When gold is assessed for its intrinsic worth, only the pure gold content matters — and the karat chart gives you that purity percentage instantly.
• Dealers and pawn shops use this chart every day. If you don't know it, you're negotiating blind.
• Karat stamps on jewelry are your starting point. A ring stamped "585" is 14K gold. Knowing the gold karat chart means you can read those stamps fluently.

The Complete Gold Karat Chart: Purity, Hallmarks & Melt Value

This gold karat chart covers every grade you'll commonly encounter. The melt value column uses a reference spot price of $3,200 per troy ounce (approximately $102.87 per gram) — adjust based on today's live spot price for exact figures.

A few important notes on reading this gold karat chart correctly:

• Melt value is the intrinsic value of the raw gold. Jewelry may sell above or below this based on craftsmanship, brand, or condition.
• The fineness stamp (417, 585, 750) is the decimal version of the purity percentage times 1,000. You'll see these stamped inside rings and on clasps.
• Gold spot price fluctuates daily. Always verify before any transaction — check our live spot price guide or the World Gold Council's real-time gold price tool for current rates.
• The US Federal Trade Commission sets minimum karat standards for what can legally be marketed as "gold" — the FTC Jeweler's Guide defines every grade on the gold karat chart officially.

10K vs 14K Gold Value: The Real Difference in Dollars

Of all the comparisons in the gold karat chart, the 10K vs 14K gold value question comes up most often — and it's where I see buyers make the most expensive mistakes. Let's break this down precisely.

At the melt level, 14K gold contains 39.7% more pure gold per gram than 10K gold (0.583 vs 0.417 grams of gold per gram of alloy). That's a significant difference in intrinsic value. But the 10K vs 14K gold value comparison gets more complicated when you factor in retail markup and resale.

When 10K Gold Makes Sense

If you're buying gold as a consumer for everyday wear, 10K can be a practical choice — it's harder, more scratch-resistant, and significantly cheaper at retail. A 10K gold chain that costs $300 retail might only be $125 in melt value. But if that same design in 14K costs $500 retail with $175 in melt value, you're not necessarily getting a better deal.

When 14K Gold Is the Better Buy

For investment purposes, or when buying second-hand, 14K gold consistently offers a better value proposition. Resale demand for 14K gold jewelry is far higher — jewelers, pawn shops, and online buyers all prefer it. A 14K piece commands better resale prices in absolute terms, and often as a percentage of melt value too.

The 10K vs 14K gold value spread becomes most visible when you're selling. I've had customers bring in 10K pieces expecting pawn shop prices similar to their 14K jewelry — and they're always surprised by the gap. The gold karat chart doesn't lie: less gold content means less payout, full stop.

10K vs 14K Gold Value Comparison Table

The following table puts the 10K vs 14K gold value comparison side by side across several practical scenarios, based on a spot price of $3,200/oz.

How to Use the Gold Karat Chart to Calculate What Your Gold Is Worth

The gold karat chart is most useful when paired with a simple formula. Here's how to calculate the melt value of any gold piece in three steps:

1. Find the karat stamp — Look inside rings, on clasps, or on the back of pendants. Note the karat (10K, 14K, 18K) or fineness number (417, 585, 750).
2. Weigh the piece — Use a digital scale that measures in grams. Accuracy to 0.1 gram is sufficient for most calculations.
3. Apply the formula — Melt value = Weight (g) × Gold spot price per gram × Purity from the gold karat chart.

Example: You have a 14K gold ring weighing 6.2 grams. Gold spot is $3,200/oz, which equals approximately $102.87 per gram. Using the gold karat chart, 14K gold is 58.3% pure.

Melt value = 6.2 × $102.87 × 0.583 = approximately $371.89.

Now you know your baseline. Any offer from a pawn shop, coin dealer, or gold buyer should be evaluated as a percentage of that melt value. In my experience buying gold for 15 years, reputable buyers offer 65–80% of melt. Anything below 50% is a lowball — and now you can walk away knowing exactly why.

Common Gold Karat Stamps to Recognize

When using the gold karat chart in the field, these are the stamps you'll encounter most often:

• 375 — 9K gold (common in UK and Australian jewelry, 37.5% pure)
• 417 — 10K gold (the minimum legal "gold" standard in the US)
• 585 — 14K gold (the most common US fine jewelry standard)
• 750 — 18K gold (European standard, luxury jewelry)
• 916 or 917 — 22K gold (South Asian bridal gold)
• 999 or 9999 — 24K gold (investment bullion)

Understanding 18K and 24K Gold on the Karat Chart

Most US buyers are familiar with 10K vs 14K gold value comparisons, but 18K and 24K gold follow their own logic — and the gold karat chart tells a different story for each.

18K Gold: The European Standard

At 75% pure, 18K gold sits at the high end of practical jewelry gold. It's the standard in European fine jewelry and is required by many luxury watch brands. From a gold karat chart perspective, 18K contains nearly 29% more gold per gram than 14K — a meaningful premium.

When buying 18K gold second-hand, you're often getting more value per dollar than retail pricing would suggest. Estate jewelry and pawn shop pieces in 18K are frequently undervalued by sellers who don't understand the gold karat chart. That's an opportunity for educated buyers.

24K Gold: Pure Bullion at the Top of the Chart

At 99.9% purity, 24K gold is the benchmark — every other position on the gold karat chart is defined relative to 24K. It's too soft for most wearable jewelry, which is why you find it almost exclusively in investment-grade coins (like American Gold Eagles at 22K, or Canadian Maple Leafs at 24K), bars, and some Asian ceremonial pieces.

The gold karat chart shows 24K at approximately $102.87 per gram at a $3,200 spot price. That's the ceiling — pure intrinsic value with minimal alloy dilution. If you're buying gold strictly as an investment, bullion-grade 24K products offer the cleanest exposure to spot price movement. The US Mint's American Gold Eagle program is one of the most trusted sources for investment-grade bullion coins.

Gold Karat Chart Mistakes That Cost Buyers Real Money

Even with a perfect gold karat chart in hand, I've seen buyers make the same costly errors again and again. Here are the most common ones:

Mistake 1: Trusting the Label, Not the Stamp

Gold-filled and gold-plated jewelry can legally be labeled with terms that sound like solid gold. A piece labeled "14K GF" is 14K gold-filled — a thin layer over a base metal, worth a tiny fraction of solid 14K. Always look for a three-digit fineness stamp (585, 750, etc.) from the gold karat chart, not just a karat designation.

Mistake 2: Ignoring Weight When Comparing the 10K vs 14K Gold Value

A heavier 10K piece can absolutely be worth more than a lighter 14K piece. Don't just compare karat grades — always multiply by weight. This is why having a pocket scale and a memorized gold karat chart is so powerful in the field.

Mistake 3: Accepting the First Offer Without Knowing Melt Value

Pawn shops and gold buyers make their margin by offering below melt value. That's fair — they're running a business. But you should know what melt value is before you walk in. Use the gold karat chart and today's spot price to calculate your baseline, and then evaluate any offer as a percentage of that number.

Mistake 4: Assuming All Gold of the Same Karat Has the Same Value

Two 14K gold rings of different weights have very different values. The gold karat chart gives you purity — weight gives you quantity. Both factors are required to calculate what any piece of gold is actually worth.
