Antique Edwardian Gold Filled Handpainted Portrait Miniature Pin Brooch

Dating to the early 1900s or so, here's a little pin I picked up in England about 25 years ago. A handpainted portrait miniature of a regency lady is set into a round rose gold filled setting. Height/width is 3/4"; weight is 3.2 grams. Condition of the portrait is very fine (not signed) while the setting does show an age of patina. The brooch can be manually cleaned with a polishing cloth but that's as far as I would go - any liquid near the watercolor would most likely result in damage. An adorable pin - perfect to wear or for a favorite doll/teddy bear.
