Call NowWhat Karat Gold Is Worth the Most When You Sell?
Is 24K always worth more than 14K? Not always. Here is what you need to know about gold karats, purity, and how to get the most cash when you sell your gold jewelry.
What Karat Gold Is Worth the Most When You Sell?
If you're sorting through a jewelry box before heading to a gold buyer, you might be wondering: does karat matter? Which pieces are worth the most? The answer is a little more nuanced than you might expect.
What Does Karat Mean?
Karat measures the purity of gold — specifically, how many parts out of 24 are pure gold. The higher the karat, the more gold content, and generally the more valuable per gram.
- 24K = 99.9% pure gold
- 22K = 91.7% pure gold
- 18K = 75% pure gold
- 14K = 58.3% pure gold
- 10K = 41.7% pure gold
Higher Karat = More Value Per Gram
When it comes to raw gold value, yes — higher karat means more money per gram. A gram of 24K gold is worth about twice as much as a gram of 10K gold, because it contains twice as much actual gold.
Here's a rough comparison at a $2,400/oz spot price:
| Karat | Gold Content | Value per gram (approx.) |
|---|---|---|
| 24K | 99.9% | ~$77 |
| 22K | 91.7% | ~$71 |
| 18K | 75% | ~$58 |
| 14K | 58.3% | ~$45 |
| 10K | 41.7% | ~$32 |
But Weight Matters Too
Here's where it gets interesting. A heavy 10K gold chain might actually be worth more total than a lightweight 18K pendant — because the chain has so much more gold by weight.
Total value = weight × karat purity × spot price
Don't assume your lighter, higher-karat piece is worth more than a heavier, lower-karat one. Bring everything in and let us weigh it.
What Karat Is Most Common in the US?
14K is by far the most common karat for American jewelry. It's the sweet spot between durability and gold content. Most rings, chains, bracelets, and earrings sold in the US over the past 50 years are 14K.
18K is more common in European and high-end jewelry. 10K is often found in budget jewelry and older pieces. 22K and 24K are more common in Asian and Middle Eastern jewelry traditions.
How to Find the Karat Stamp
Look for a small hallmark stamped on your jewelry:
- Inside the band of a ring
- On the clasp of a necklace or bracelet
- On the back of a pendant or earring post
Common stamps:
- 10K, 14K, 18K, 22K, 24K — straightforward US stamps
- 417 = 10K | 585 = 14K | 750 = 18K | 916 = 22K | 999 = 24K
- GF = Gold Filled (not solid gold — much lower value)
- GP = Gold Plated (not solid gold — very low value)
Gold Filled and Gold Plated: What to Know
Gold filled and gold plated jewelry are NOT the same as solid gold. They have a thin layer of gold over a base metal.
- Gold plated: Very thin layer, usually less than 0.5 microns. Worth very little as scrap.
- Gold filled: Thicker layer, legally required to be at least 5% gold by weight. Has some scrap value, but much less than solid gold.
