Why 18K Gold Dominates in UK

18K is the standard for fine British jewellery — engagement rings, wedding bands and designer pieces in the UK are overwhelmingly 18K (750 fineness), hallmarked by one of the four UK assay offices. It is hard enough for daily wear and stone-setting, and its warm colour suits the British market's taste.

What 18K Gold Is Used For

Engagement rings, wedding bands, and fine and designer jewellery from British high-street and independent jewellers.

How to Buy 18K Gold in UK

Check for the 750 hallmark and the assay office mark — UK hallmarking is a legal guarantee of fineness. 18K jewellery carries 20% VAT when bought new from a retailer, and making charges vary widely, so compare. For investment, 18K is a poor choice — buy 24K bars or sovereigns instead; 18K is for wearing.
