Pretty guilloche enamel bar pin featuring a floral design in green on white translucent background. Looks like brass but is unmarked, and e pin mechanism is silver tone, so may be a replacement. Nice slightly curved shape. Size is 2 1/2" x 1/4". Condition is good but there is a very tiny space of enamel loss as shown, and the pin remains loose in the clasp, probably the wrong size.
