75% pure · 18/24 · hallmarked 75018K is three-quarters gold, stamped 750, and it is the international standard for fine jewellery — what most European and designer houses work in. A quarter of the metal is alloy, making it noticeably harder than 21K or 22K and far better at holding a polished edge.
That hardness is why gem-set pieces are usually 18K: prongs holding a diamond have to stay where they were bent, and softer gold lets stones work loose. It is also the karat that carries colour — a copper-heavy mix gives rose gold, palladium or nickel gives white gold.
Priced per gram it looks cheaper than 21K, but that is arithmetic, not a discount: you are buying a quarter less gold. Sold back, the shop pays on 75% of the weight — so compare 18K against 21K by gold content, never by the sticker.
In Brazil, 18K is the karat the retail trade is built around, so it is the one you will be quoted first and the one with the deepest buy-back market.
