Gold tone leaf brooch mixed textured numbered excellent vintage pin ll3353

This lovely pin is feminine and simply designed. It is a single ovate leaf with a gold frame. The frame has a sand-blasted finish; the leaf is striated with a Florentine finish and the stem has a matte polished ridge. On the back is a safety clasp.

The pin has a number etched into the back. I believe it is 0773. The 3 might be an 8. There is no designer name.

Condition is excellent vintage. No problems.
The brooch is 1.75 inches long.
