Wondering whether a gold buyer is testing your jewellery properly before making an offer? This page shows how Cash4gold-Now uses XRF scanning technology to check the purity of gold, platinum and palladium before we calculate your valuation.
You’ll see how the process works, why XRF testing is widely used for precious metal analysis, and how it helps us assess items quickly and accurately when you sell by post in the UK.
If you’re comparing gold buyers, this is the part that matters. This short video walks you through how jewellery moves from arrival, to purity testing, to a final offer based on current precious metal value.
It is designed to help you understand that the valuation process is based on real testing rather than guesswork. That distinction matters when you’re posting valuables and want proof that the process is credible.
When someone sends gold jewellery, coins, bullion or other precious metals to a postal gold buyer, the value depends on what the item is actually made of, not just how it looks or what the hallmark stamp claims.
Accurate purity testing is therefore central to a fair valuation, because it tells us how much of the item is real gold, platinum or palladium and how much is made up of other, lower-value metals.
For example, two rings that look identical could be very different in value if one is 9ct gold and the other is 18ct. So a proper test makes sure you are not being paid as if everything was the cheaper option. By checking purity carefully before making an offer, a good gold buyer can explain clearly what they are paying you for and give you more confidence that the price you are offered is based on the true metal content rather than guesswork or rough visual checks.
When we receive a completed gold selling pack, items are valued by experienced staff. Offers are based on purity and a percentage of the spot prices as set by London Bullion Market Association for the day the items are received.
XRF analysis helps support that process by identifying the elemental composition of precious metals quickly and without relying only on older acid-based methods.
Here’s how to cash in your gold, platinum and palladium with us:
XRF (X-ray fluorescence) testing fires a controlled X-ray beam at your jewellery and measures the energy that bounces back from the metal. Different metals give off different energy patterns, so the analyser can identify what percentage of the item is made up of gold, platinum, palladium and other alloy metals. It is non-destructive, fast, and gives a clear purity reading that helps us value your jewellery fairly before we make an offer.
Traditional acid testing can give a rough indication of purity, but it depends heavily on the operator, only tests a small area and can mark softer items. XRF testing is non-destructive and reads the metal composition in more detail, which means a clearer picture of what the item is actually made of. In practice, XRF is a more modern, consistent and customer-friendly way to assess precious metal content, especially when you are selling gold by post and want a reliable process.
Yes, we use XRF analysis to test gold, platinum and palladium jewellery before we calculate your valuation. The analyser looks at the full metal mix in each item, so we can see the precious metal content rather than just relying on a stamped hallmark. This helps make sure items that contain platinum or palladium, as well as gold, are assessed properly before we make you an offer.
First, we test your jewellery to check the purity of the gold, platinum and palladium it contains. We then group items by metal type and purity and apply live precious metal prices for that day to work out the intrinsic metal value. From there, we calculate your offer and contact you with a clear figure; if you accept, we send the money straight to your bank, with 1 hour bank transfer once you accept our offer. If you decide not to go ahead, we return your items free of charge using secure, insured post.
You start by ordering your free gold selling pack so you can send your gold, platinum and palladium jewellery to us securely. You then use the secure, insured Royal Mail service included in your pack to post your items to our valuation team. Once your jewellery arrives, we test and value it, then send you an offer based on purity and live metal prices; if you are happy with the offer, you approve it and we arrange a 1 hour bank transfer once you accept our offer.
