Foreign and unhallmarked gold can be difficult to assess from its markings alone. At Trentham Jewellery Centre, we use professional XRF testing to help identify the gold content of your jewellery and provide a clear valuation based on its purity, weight and the current gold market.
No appointment needed. No pressure to sell. Immediate payment available if you proceed.
Gold bought abroad may be marked differently from UK-hallmarked jewellery or may have no visible hallmark at all. It may also be handmade, sold by weight or manufactured using traditional methods.
This does not mean the item is lower purity. However, unfamiliar markings can make professional testing particularly important.
Your foreign gold should be valued according to what it actually contains—not automatically treated as 9ct because it lacks a familiar UK hallmark.
XRF testing is a non-destructive method used to analyse the metal content of an item. It helps us assess the likely purity of suitable foreign and unhallmarked gold without cutting, filing or damaging the jewellery.
We use the results alongside a physical inspection, the item’s weight and any visible markings to provide a clear and informed valuation.
Foreign gold can carry unfamiliar markings or no hallmark at all. Watch our short video to learn why professional testing is important before accepting an offer.
We assess a wide range of gold purities, including:
Foreign gold may also display fineness marks such as 375, 585, 750, 916 or 999.
Wherever possible, your jewellery will be valued according to its identified gold content rather than being automatically categorised as standard UK 9ct gold.
No. Turkish gold can vary considerably in purity.
Many Turkish jewellery pieces are made from 14ct gold, while others may be 18ct, 21ct, 22ct or another purity. Manufacturing styles and markings can also differ from those commonly found on UK jewellery.
Proper testing is the best way to understand what your Turkish gold contains before deciding whether to sell.
