This lovely maple leaf pin was produced by Avon in the mid-1980's. The pin is called Dew Touch and there is a single soft rhinestone set into the leaf like a soft dew drop. The color is a lovely variegated green. The pin is marked Avon on the back and the closure is a safety c-clasp.
The pin can be seen on page 154 in "Identifying Avon Jewelry" by Sandra Sturdivant.
