A Guide to UK Hallmarking & The SF Sponsor Mark

🏛️ The Mark of Excellence: Why We Hallmark Our Jewellery

At Sofitgold, we believe that luxury is built on trust. Whether you are falling in love with a pre-owned vintage treasure or a sleek new design, you deserve to know exactly what you are investing in.

In the UK, the law is very clear: any gold item weighing over 1 gram must carry a full English hallmark. This isn’t just a formality; it is your guarantee of purity and quality.

🔬 Going the Extra Mile for Authenticity

Many vintage or pre-owned pieces come to us with "10k" or "14k" stamps from abroad, or sometimes no marks at all. While others might sell these as they are, we choose a different path.

If an item doesn't meet the strict UK hallmarking standards, we take it directly to the London Assay Office. There, it is independently tested (assayed) and struck with our own Sponsor Mark. This means:

  • Total Transparency: If a piece is stamped "10k" but tests as 9ct gold, we hallmark it as 9ct and sell it as such. We believe in honesty over everything else.
  • London Heritage: Your jewellery will bear the iconic Leopard’s Head, the mark of the London Assay Office, ensuring it has been verified by the world’s most prestigious testing house.
  • Guaranteed Purity: When you see our mark, you know the metal has been scientifically proven to be genuine.

✨ Luxury You Can Trust

We don't just sell jewellery; we preserve it. By ensuring every piece—new or pre-owned—is fully hallmarked, we are protecting your investment for years to come.

When you shop with Sofitgold, you aren't just buying a beautiful accessory; you’re buying peace of mind, authenticated by centuries of British tradition.
