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. Identity and payment requirements

A merchant may require identity evidence because of law, policy or transaction size. Payment methods and cash limits can also differ. Confirm directly before visiting and provide only data necessary for the transaction.

5. Compare and time it

Terms can differ on the same day. Use the comparison method and directory, then obtain directly comparable quotes.
The market trend provides context, but short-term prices alone should not determine a decision.

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.

How is net sale proceeds calculated — and is it a good deal?

When selling old gold, the "headline price" is not the "net proceeds." Net proceeds are only accurate after deducting commission and melt loss (weight deduction) from the shop's buy-back quote. This calculator's logic: enter the shop's per-tael buy-back quote, the item's grams and purity, and it estimates expected net proceeds, then compares against the international spot benchmark (same purity) to give a rough "good / fair / poor." Simplified: net ≈ shop buy price × weight(tael) × purity × (1 − commission/melt loss).

Who is it for? Anyone with old jewellery or bars to sell who wants a pre-estimate and to avoid being misled by headline numbers. How to read it? All figures are reference estimates, not any shop's official or dealing price; actual proceeds depend on on-site fineness testing, non-gold parts, solder points and each shop's deductions. Ask several shops and follow the on-site quote.
