Sell Gold per Gram: What You Need to Know
If you want to sell gold per gram, you need to understand weight, purity and the buyer’s rate. These factors determine the value of most gold jewellery, coins and scrap. However, the headline market price is not usually the same as the final purchase offer.
This guide explains how per-gram gold valuations work in the UK. In addition, it shows how to compare buyers, fees, postage and payment terms before selling.
How Buyers Calculate Gold Value per Gram
A buyer starts by weighing the item. Next, the buyer identifies its purity or fineness. Finally, the buyer applies the relevant purchase rate for that type of gold.
For example, 10 grams of 9ct gold does not contain 10 grams of pure gold. A 375 hallmark means that the alloy contains at least 37.5% gold. Therefore, the item contains approximately 3.75 grams of gold before any non-gold components receive separate consideration.
Stones, clasps, watch movements and other parts may add weight without adding payable gold. Consequently, a professional valuation can differ from a calculation based on the item’s total weight.
Purity Matters When You Sell Gold per Gram
Gold purity affects the per-gram rate because higher-carat gold contains more precious metal. UK buyers commonly assess jewellery marked 375, 585, 750, 916 or 999.
| Gold type | Fineness mark | Minimum gold content |
|---|---|---|
| 9ct | 375 | 37.5% |
| 14ct | 585 | 58.5% |
| 18ct | 750 | 75% |
| 22ct | 916 | 91.6% |
| 24ct | 999 | 99.9% |
Nevertheless, a visible stamp does not always provide enough information. Marks can wear away, and some foreign items use different systems. As a result, buyers may test the item before confirming its purity.
Check the Current UK Gold Price
When you sell gold per gram, current market information provides an important reference point. Gold prices move throughout the trading day. Therefore, check the latest information before requesting an offer. The Royal Mint UK gold-price chart displays the market price in pounds per troy ounce.
However, that market figure is a reference price rather than a guaranteed jewellery-buying rate. Buyers must account for purity, testing, refining and their commercial terms.
You can also use the Moonstone Gold gold price calculator for an initial estimate. Afterwards, compare the estimate with an item-specific valuation.
Estimate Value Before You Sell Gold per Gram
You can make a rough estimate at home by following these steps:
- Check the hallmark: first, identify the carat or fineness mark.
- Group matching items: keep different purities separate.
- Record the weight: next, weigh each group in grams.
- Check the relevant rate: use a price for the correct carat.
- Calculate an estimate: multiply the group weight by the indicative per-gram rate.
For instance, do not apply an 18ct rate to an item marked 375. Moreover, remember that home scales and visible hallmarks can only provide an estimate.
Compare Buyers Before You Sell Gold per Gram
Different buyers may offer different per-gram rates. Their testing methods, refining arrangements and operating costs can vary. Therefore, compare the complete offer rather than one advertised number.
When comparing buyers, check:
- The rate for your specific gold purity
- How the buyer measures eligible weight
- Whether fees or deductions apply
- Whether postage is tracked and insured
- How quickly payment follows acceptance
- What happens if you decline the valuation
Most importantly, ask the buyer to explain any difference between an estimate and the final offer. Clear terms make comparisons easier.
Online and In-Person Gold Buyers
You can sell gold through a high-street buyer or an online postal service. Each method has advantages and limitations.
High-Street Buyers
An in-person buyer may provide a valuation while you wait. However, opening hours and travel can make the process less convenient. You should also compare the offered rate before accepting.
Online Gold Buyers
An online buyer allows you to begin from home. In addition, some services provide tracked and insured postage instructions. Before sending anything, review the insurance limits, packaging requirements and returns policy.
If you plan to sell gold per gram online, retain your proof of posting and tracking information. Then keep the valuation and payment confirmation for your records.
Prepare Gold for an Accurate Valuation
If you plan to sell gold per gram, you do not need to polish items before requesting a metal-value assessment. In fact, harsh chemicals can damage jewellery or affect stones. Instead, leave testing and assessment to the buyer.
Group items by hallmark where possible, but do not remove stones or components yourself. Moreover, photograph the items before packaging them for a postal valuation.
Review the Offer When You Sell Gold per Gram
After testing, the buyer should provide a confirmed valuation. Check the eligible weight, purity and final amount before accepting. If the details remain unclear, ask for an explanation.
Once you accept, the buyer should arrange payment under its published terms. Alternatively, if you decline, follow the stated return process. Therefore, read both the payment and return terms before sending your gold.
