"925" stamp can be used to mark 925 Sterling Silver. The stamp is cut
into 0.25” (7mm) hardened steel square stock. The size of the "925"
is 1.0x3.0 mm. It is bent to allow ease of positioning inside rings or other
hard-to-reach areas, but also works perfectly on flat areas. The stamp is 3.38”
(85 mm) long and has a beveled top for striking with a heavy mallet.
