What 18K actually means

It is the karat where the gap between metal value and retail price is widest. An 18K designer ring can retail for several thousand dollars and carry two or three hundred dollars of gold. That is not a scam; it is what you are paying for design, brand, and stones. But it means a scrap quote will feel shockingly low, and the shock is the gap between the two prices, not evidence of a lowball offer.

Before selling an 18K piece for scrap, check whether it has a maker. A signed piece from a recognised house often sells for multiples of melt on the secondary market.

European pieces are usually stamped 750 rather than 18K. Same thing.

Questions people ask

How much is 18K gold worth per gram today?
18K gold is worth $99.48 per gram right now. It is 75.00% pure, so each gram contains 0.7500 grams of actual gold, valued at the live spot price of $4,125.39 per troy ounce.
How much is a 18K gold chain or ring worth?
It depends entirely on weight, so weigh it first. As a guide at today's price: thin chain (16–18in) (2 – 5 g) is roughly $198.95 to $497.38; medium chain (20in) (8 – 20 g) is roughly $795.81 to $1,989.52; heavy rope chain (25 – 60 g) is roughly $2,486.89 to $5,968.55. These are metal values, not offers.
Is 18K gold real gold?
Yes. 18K means 18 parts in 24 are gold, or 75.00% by weight. The rest is alloy metal added for hardness and colour - pure gold is too soft to hold a stone or survive daily wear.
What hallmark is stamped on 18K gold?
European pieces are usually stamped 750 rather than 18K. Same thing.
Will a gold buyer pay me this amount?
No, and any site implying otherwise is misleading you. This is the melt value - what the metal alone is worth at spot. Refining, testing and the buyer's margin all come out of it, so a real offer is a percentage of this figure. Treat it as the ceiling and get more than one quote.
How current is this price?
The calculation uses the live spot price, currently $4,125.39 per troy ounce from swissquote, read at 18:45 UTC. It is not a cached daily figure.
