Selling gold in Hong Kong: purity, weighing loss, commission, ID

Original content · last updated 2026

Selling gold looks simple, but several factors affect your final net. Sort these out before selling so you don't lose out.

1. Purity

Pure gold 999.9/999 (24K) has the highest content; 22K (916) ≈ 91.6%, 18K (750) 75%, 14K (585) 58.5%. Shops pay by purity, and gemstones or clasps on jewellery usually aren't counted as gold.

2. Weighing loss

Some shops cite "weighing loss" on old gold — deducting a weight or percentage for melting loss. Ask the exact %, and enter it under "commission / weighing loss" above.

3. Commission / fees

Some shops or banks charge a commission when you sell. Together with weighing loss, that's the gap between the quote and your net.

4. Bring your ID

For selling (especially larger amounts), shops usually require photo ID for registration — remember to bring it. Some pay by bank transfer or cap cash payouts.

5. Compare and time it

Net formula: net ≈ buy-back quote (per tael) × weight (tael) × purity × (1 − commission/weighing loss). 1 tael = 37.429 g.
Results and benchmark are reference prices / estimates; the international benchmark is the pure spot value, not any shop's dealing price, and not investment advice. The shop's on-site quote and terms prevail.
