About 9K gold
9K gold, usually written 9ct in the UK, is 37.5% gold and stamped 375. It's the lowest fineness that can be hallmarked as gold in the UK and is common in British and Australian jewelry.
It can't be sold as "gold" in the United States, where the minimum is 10K, so a 9ct piece bought abroad may be marked differently if it's resold in the US.
9K gold price per gram = spot price per gram × 0.375. The live 9K price per gram and per ounce is at the top of this page.
How to calculate the value of gold
Gold jewelry is an alloy, so only part of its weight is gold. Its melt value is the pure gold it contains, priced at the spot price:
purity = karat ÷ 24 (24K is refined to 99.9%) pure gold (g) = weight (g) × purity price per gram = spot price per troy oz ÷ 31.1035 melt value = pure gold (g) × price per gram
So a 14K gold bracelet weighing 10 grams holds 10 × 58.3% = 5.83 grams of pure gold, and is worth 5.83 times today's gold price per gram. That's the floor for what the gold is worth. A shop's price adds design, labor and margin on top, and a scrap buyer's offer usually sits below it.

| 24K gold price | 99.9% | 999 |
| 22K gold price | 91.7% | 916 |
| 21K gold price | 87.5% | 875 |

| 10K gold price | 41.7% | 417 |

How to use the gold calculator
- 1
Find the karat
Look for a stamp on the clasp, inside a ring band or on a tag: 10K, 14K, 18K, or a fineness number like 585 or 750. Pick it in the karat menu.
- 2
Weigh the item
Use a jewelry scale in grams if you can. Kitchen-scale ounces, troy ounces, pennyweight, kilograms and tola are all supported.
- 3
Subtract anything that isn't gold
Stones, pearls and steel parts add weight but no gold. Enter their weight so they're left out of the value.
- 4
Read the melt value
The calculator multiplies pure gold content by the live spot price. Add a price you were quoted to see how it compares.

Frequently asked questions
- How much is 9K gold worth per gram?
- 9K gold is 37.5% pure gold, so one gram of 9K is worth 0.375 × today's price of a gram of pure gold. The live 9K gold price per gram is at the top of this page and refreshes every minute; switch the currency to see it in euros, pounds, rupees and 14 other currencies.
- How do I calculate the value of 9K gold jewelry?
- Weigh the piece in grams, subtract anything that isn't gold (stones, pearls, steel springs), then multiply by 0.375 to get grams of pure gold. Multiply that by the spot price per gram for its melt value. The calculator above does all of it once you enter the weight.
- What does a 375 stamp mean?
- It's the fineness hallmark for 9K gold: parts of pure gold per 1,000. A piece stamped 375 is 37.5% gold, the same as one stamped 9K. Stamps can be wrong or fake, so a jeweler's acid or XRF test is the way to confirm purity before selling.
- Is 9ct gold the same as 9K?
- Yes. "ct" (carat) is the British spelling of karat when it describes gold purity, so 9ct and 9K both mean 9 parts gold out of 24, or 37.5%. Don't confuse it with the carat used to weigh gemstones, which is a unit of weight (0.2 grams).
