The London fixing, the troy ounce, the alloy's fineness: what separates the published price from the price of a gram of your alloy. Liink does not show live prices for now.
Liink does not show live metal prices for now. Ask your refiner for your daily rate: it publishes its buying and selling prices for fine metal every day, often in euros per kilo.
To get from that rate to the cost of a piece, enter it in the material cost calculator: it applies the alloy's fineness, the loss and the stones.
Open the material cost calculatorA metal price is not a purchase price. Three gaps separate the figure quoted in London from the amount you pay your supplier, and each one is measured in percent.
The London fixing is quoted per troy ounce, which is 31.1035 grams. The commercial ounce is 28.35. Dividing by the wrong one puts you almost 10% out on every gram, in the direction that costs money.
The fixing quotes metal at 999.9 parts per thousand. An 18-carat gold is 750: its fine content is therefore worth only 75% of the price. The remaining quarter is the other metals in the alloy, which have their own prices — significant in palladium white gold, negligible in copper.
Between the fixing and the invoice come the supplier premium, the delivered form (grain, sheet, drawn wire), the quantity, and the EUR/USD rate since the fixing is quoted in dollars. That is exactly why the material cost calculator accepts your own price per gram: the fixing is a reference, not your price.
On the fixing, the units, and getting to a real price.
The gold fixing takes place twice a day in London, at 10:30 and 15:00 local time; silver once, at noon; platinum and palladium at 9:45 and 14:00. It is a daily reference, not a live feed, and Liink does not display it: ask your refiner for your daily rate.
The reference market for precious metals is quoted in dollars per troy ounce. The price in euros therefore depends on two things that move independently: the metal itself and the EUR/USD rate. A price flat in dollars can rise in euros without a gram of gold changing value.
Multiply the price per gram by the fineness: an 18-carat gold contains 750 parts per thousand of fine gold. Then add the other alloy metals in proportion. The material cost calculator does both, using the alloys common in jewelry.
As a reference and as an argument, yes. As a purchase price, no: your supplier applies its premium and its charges. A quote is built on your real price, the one on your last invoice: that is the one you enter in the calculator.
Because its demand is industrial before it is decorative: most of it goes into catalytic converters. Its price follows the car industry more than jewelry, which makes it markedly more volatile than gold.
Liink connects jewelry brands with their workshops: orders, production tracking, weight accounts and the statutory register.
