The Sterling Sauteur Renoir line of jewelry is highly collectible. It was made for a short period of time from the mid '50s to early '60s. Very cool brooch that looks to be a tree with leaves. There is lots of detail. Some wear marks on the front but it looks like part of the tree trunk. Pin mechanism is in good working condition. The brooch measures 3 x 2 1/4. Thanks so much for looking. Email with any questions.
