Gold content is the item weight times karat over 24, valued at the pure gold price per gram, with the making charge applied as a percentage of that gold value. Because 18 karat is only 75% gold, the metal in an 18 K piece is worth a quarter less than the same weight in 24 K, which is where buyers most often lose out.
