Here's the specification sizes for this stamping. They are 3 (78mm) by 1 (25mm) inches and are lightly dapped for depth. I can see them bring used for earrings. I'd add rhinestones into the piece for added drama. They are raw brass and are ready for a patina or paint. They will oxidize over a period of time, but brush up to bright golden color if you use a steel wool (size 0000) pad on them.
