What does 925 CZ mean on jewelry
In a 925 CZ stamp, a CZ-set ring may carry both inside its shank. EPNS and ALPACA describe different base-metal constructions from sterling.
Reading the metal designation
CZ is not a second silver purity grade. It names a manufactured gemstone material; the metal mark and stone abbreviation should be read separately. A CZ-set ring may carry both inside its shank.
What to check next
EPNS and ALPACA describe different base-metal constructions from sterling. A silver standard can still appear on a gilded silver object. Check the mark on the main piece as well as detachable fittings, then use the separate signature to look up its maker.
