How to Sell Gold in the UK (9K, Hallmarks & Fair Offers)

British gold jewellery is usually stamped with a fineness number—most often 375 for 9K, 585 for 14K, or 750 for 18K. Before you accept a quote in pounds, estimate melt value from live spot gold and the USD→GBP rate, then ask each buyer what percentage of melt they pay.

Step 1 — Find the hallmark

Look inside rings, near clasps, or on the back of pendants. UK pieces often show a three-digit fineness (375, 585, 750) plus optional Assay Office marks. If you see 375, that is 9K gold—the legal minimum sold as gold in the UK. See our hallmarks guide and karat chart if the stamp is unclear.

Step 2 — Weigh in grams

Use a 0.01 g jewellery scale. Weigh gold-only metal if you can safely remove stones or steel clasps. Separate mixed fineness—do not blend 375 and 750 into one total before comparing quotes.

Step 3 — Estimate melt in pounds

Melt ≈ weight (g) × fineness per-gram rate × USD→GBP conversion. Our GBP melt pages and scrap gold calculator use the same live spot basis. This is your benchmark—not what a shop will pay.

Step 4 — Compare UK buyer types

• Pawnbrokers — often ~50–70% of melt for quick cash; see 9K pawn estimates.
• High-street cash-for-gold — convenient but ask for % of melt in writing.
• Mail-in / online buyers — may pay a higher % on weight but allow time for assay and insured postage.

Step 5 — Get multiple offers

Ask: "What percentage of melt are you paying today?" If an offer is far below your GBP melt estimate with no clear reason (mixed metals, stones, etc.), walk away. For a US-focused checklist that still applies to sorting and weighing, see how to sell gold.
