1-5/8" long .925 quality marking stamp for wet clay. A "quality mark" is the little number or letters that indicate what metal and purity is used in an item made of a precious metal. By law, this stamp can only be used to mark an item that is made from .925 Silver.
Each stamp has been calibrated with placement, legibility and shrinkage of clay in mind. Sized at just 2mm x 4.8mm, placement is easier than ever.

"I don’t know how I ever missed this on the Cool Tools website. I roll out my clay 2 cards thick, stamp a bunch of these, cut them out, let them dry and file them. That way they are always on hand when I go to hallmark my work. This 925 stamp is the perfect size for earrings, rings and pendants."
