Vintage Green guilloche enamel sterling silver lucky shamrock. 

This came from a Victorian / Edwardian charm bracelet with marks dating from the early 1800s to 1910 so I believe it to be an early antique charm. Marked “STERLING” on the back of the charm.

No makers mark and I have been unable to find an identical example.

Charm measures 15 mm x 12 mm.

In excellent condition. Light patina to the back of the charm. I do not clean the charms I sell for buyers that prefer vintage / antique items to have their original patina.

From a smoke free home.
