Jewellery, gold and diamonds
How jewellery is priced
A ring's shop price is five numbers stacked on top of each other. Once you see them separately you can judge any quote, and you can see why the same ring costs a third to make and a fifth to sell back.
1. Metal at spot
Gold is priced per gram of pure gold, worldwide, every minute. A karat is a purity: 18K is 75% gold, 14K 58.5%, 9K 37.5%. Multiply the piece's grams by purity by today's price per gram and you have the metal value. Makers pay a few percent over spot for casting-grade alloy and lose 5–10% to sprues and polishing; both are small lines in the estimate.
2. Stones at trade prices
Diamonds are priced per carat by size bracket, colour and clarity; coloured stones by type and quality. Trade prices are what a jeweller pays; the retail price of the stone alone is typically 1.3–1.6 × trade, a thinner margin than on metal and making because stones are a commodity anyone can compare.
3. Making
Casting, assembly, stone setting, polishing, rhodium plating and engraving are hours at a workshop rate. Setting is the big variable: a pavé stone takes three to four minutes; a centre stone 25–35; a hand-carved motif well over an hour. Rates range from about $12 an hour in some Asian workshops to $80 in Switzerland, which is why “where” changes the making cost by a factor of five while the metal stays the same.
4. Margins
The maker sells to a shop at about 1.35 × cost (wholesale). The shop sells at 1.8–2 × wholesale for metal and making, less for the stones. Designer brands multiply the whole thing by 1.3–1.5; luxury houses by 2–3. None of this is hidden; it is what pays for the shop, the staff and the risk of stock that does not sell.
5. Tax
VAT or sales tax is added at the end and varies from 0% (Hong Kong, some US states) to 25% (Scandinavia). India charges 3% GST on gold jewellery. Kubikly keeps a table of about 55 countries and shows the rate on every price.
The three prices you actually need
| Situation | Headline | What it includes |
|---|---|---|
| Buying new | Retail incl. VAT | Everything above |
| Selling pre-owned | Resale value | Metal at scrap payout (about 85% of spot) + stones at about a third of retail |
| Having it made | Manufacturing cost | Materials + workshop hours, no margins |
The estimate switches between them with one tap, and every line shows whether it came from the spot price, a trade table, your own input or an assumption.
Frequently asked
- Why is resale so much lower than retail?
- Because resale strips out making, margins and VAT and pays scrap rates for the metal. Only the materials come back, and stones come back at a third.
- What does it cost to make a ring?
- For a simple solitaire, two to three workshop hours plus materials; the estimate prices it for the country you pick and lists every line.
- Does brand really double the price?
- For luxury houses, often more. The estimate has a brand factor you can switch on to see it.
