How much is 18K gold worth per gram compared to 14K?
Always more: 18K is 75 percent pure against 14K's 58.5 percent, so at the same weight an 18K piece carries about a quarter more gold. Both are priced from the same live spot; only the purity fraction differs.
Is 750 gold the same as 18K?
Yes. "750" is the millesimal mark meaning 750 parts per thousand of pure gold, exactly 18 of 24 karats. European and imported jewelry usually carries the 750 stamp where American pieces say 18K.
Do you pay the 18K price shown on this page?
This page shows the live melt reference. A real offer is weight times tested purity times this price, minus a stated margin, with the arithmetic shown at the counter, and designer or antique pieces are priced above their metal when they deserve it.
My piece has no stamp. Could it still be 18K?
Yes, often. Older, handmade and imported jewelry frequently was never stamped, and stamps wear off. The in-store XRF reading settles the true purity in about two minutes without damaging the piece.
What is the 18k gold price per gram at a pawn shop?
Pawn shops price from the same live spot market this page tracks, but reselling gold is not their core business, so their offers typically sit toward the lower end of the payout range. The live 18K per-gram figure is in the table above; our counters pay on that same reference, weight times 75 percent purity times the live price, with the arithmetic shown as it happens.
What is the 18K gold price per pennyweight?
Right now one pennyweight of 18K gold holds $156.23 of gold at the live spot price.
