Introduction to the Gold Purity Calculator
When it comes to selling your scrap gold in the UK, one of the most important factors that determine the value is the purity of the gold. Just like scrap gold calculator, a Gold Purity Calculator is a useful tool that helps UK residents estimate the value of their gold items by factoring in the gold’s purity, weight, and current market prices. Whether you’re clearing out old jewellery, broken gold items, or selling gold coins, the calculator provides an accurate estimate of your gold’s worth, helping you make informed decisions.
Understanding the purity of your gold is crucial because the higher the purity, the more valuable the gold. In this guide, we’ll cover everything you need to know about gold purity, how it impacts the value of your scrap gold, and how to use a Gold Purity Calculator to estimate your gold’s worth in the UK.
What is Gold Purity?
Gold purity refers to the percentage of gold content in an item. Pure gold is measured in carats (ct) or in terms of its fineness. For example, 24-carat gold is considered pure gold, while lower carat gold contains other metals mixed with gold, which affects its value.
Carat System in the UK
In the UK, the purity of gold is expressed using the carat system. Here’s a breakdown of the most common gold purities found in the UK:
- 9ct Gold: 37.5% pure gold
- 14ct Gold: 58.3% pure gold
- 18ct Gold: 75% pure gold
- 22ct Gold: 91.6% pure gold
- 24ct Gold: 99.9% pure gold (pure gold)
In the UK, gold that is marked as 9ct, 14ct, 18ct, or 22ct is often used in jewellery, while 24ct gold is mostly used in gold bars or coins.
Gold Fineness
Gold fineness is another way to measure gold purity. It’s represented as parts per thousand of pure gold in an item. For example:
- 9ct gold has a fineness of 375 (out of 1000), meaning 37.5% of the item is pure gold.
- 18ct gold has a fineness of 750, meaning 75% of the item is pure gold.
How Gold Purity Affects the Value of Scrap Gold
Gold purity plays a critical role in determining the value of your scrap gold. The higher the purity, the more valuable your gold is, as it contains a greater percentage of pure gold.
Why Purity Matters in the UK
When you sell your gold, buyers typically offer a price based on the purity of the gold. In the UK, gold prices are set based on the market price for pure gold (24ct). When your gold is less pure, the value decreases because there is less gold in the item.
Example:
- If the market price for pure 24ct gold is £50 per gram, then:
- 18ct gold (75% pure) will be worth £37.50 per gram (75% of £50).
- 9ct gold (37.5% pure) will be worth £18.75 per gram (37.5% of £50).
Knowing the purity of your gold helps you understand how much you can expect to receive when you sell it in the UK. For example, if you have a piece of 9ct gold jewellery, it will be worth significantly less than the same weight in 18ct or 24ct gold.
Why is Knowing Gold Purity Important?
1. Accurate Valuation in the UK Market
The Gold Purity Calculator helps you get an accurate valuation based on the purity of your gold. Understanding the purity ensures you’re getting the correct price based on the current market price of gold. If you overestimate or underestimate your gold’s purity, you could either lose money or sell it for less than its true worth.
2. Avoid Overestimating or Underestimating the Value
If you’re unsure about the purity of your gold, using the calculator with incorrect information could lead to inaccurate estimates. For example, if you mistakenly believe your gold is 18ct when it’s only 14ct, you could be overvaluing it and making decisions based on incorrect data.
3. Sell Your Gold for the Right Price
When selling gold, whether to a local jeweller, online gold buyer, or bullion dealer in the UK, the price offered will be based on the purity of your gold. If you’ve used a Gold Purity Calculator and know the accurate purity, you’ll be in a better position to negotiate a fair price.
Using the Gold Purity Calculator
The Gold Purity Calculator is a straightforward tool that helps you determine the estimated value of your scrap gold in the UK. Here’s how you can use it:
Step-by-Step Guide:
- Weigh Your Gold:
Use a digital jeweller’s scale to weigh your gold in grams. Ensure that your scale is precise and that you measure your gold without any gemstones or non-gold materials. - Determine the Purity (Carat):
Find the purity of your gold by looking for a hallmark, such as “375” for 9ct, “750” for 18ct, or “999” for 24ct gold. If you can’t find a hallmark, use a gold testing kit or visit a jeweller to have your gold tested. - Input the Weight and Purity into the Calculator:
Enter the weight of your gold (in grams) and the purity (carat) into the calculator. The calculator will use this information along with the latest market price for gold to estimate the value of your gold. - Get the Value:
Click the “Calculate” button, and the calculator will instantly show you the estimated value of your gold based on its purity and weight.
This quick process helps you get a reliable estimate for your scrap gold and gives you confidence when you’re ready to sell it.
How to Identify Gold Purity (Carat and Hallmarks)
If you’re unsure about the purity of your gold, here are a few tips to help identify it:
1. Look for Hallmarks
UK gold jewellery often has a hallmark that indicates its purity. Some common hallmarks include:
- 375: 9ct gold
- 585: 14ct gold
- 750: 18ct gold
- 916: 22ct gold
- 999: 24ct gold
These marks represent the percentage of pure gold in the item. For example, 750 means the item contains 75% pure gold, which is 18ct gold.
2. Use a Gold Testing Kit
If your gold doesn’t have a hallmark, you can use a gold testing kit. These kits are affordable and can give you a quick estimate of the purity of your gold based on a chemical reaction.
3. Professional Gold Testing
For the most accurate results, you can visit a local jeweller who can test the purity of your gold using methods like X-ray fluorescence (XRF) or acid testing. These professional tests will give you an exact purity reading.

Q5: Does the calculator account for stones and other non-gold elements in my item?
No, the Gold Purity Calculator only calculates the value of the gold content. Any gemstones or non-gold materials in your item are not considered in the estimate. You will need to remove or deduct the weight of these elements for an accurate gold value.
