14K and 585
The karat figure counts gold parts out of 24. 585 is the corresponding common fineness stamp for the 14K grade, specified at 58.5%. KP is read together; P does not stand for plated here. Rings often carry the stamp inside the band; chains may carry it on an end tab or clasp.
What to check next
14K GF, 14K RGP and 14K HGE describe the gold layer over another metal. Retain the suffix when reading a small stamp. Compare a worn K with the letters in any maker signature beside it; the maker initials and the purity mark answer separate questions.
