This is a lovely vintage hand painted portrait brooch set in an 800 silver frame. The portrait is under glass and the frame is ornate. It dates to the early 20th century and is most likely Italian in origin. It has a locking pin mechanism and it also has a bail so that it can be worn as a pendant on a necklace. It is marked 800 on the back for 800 silver which is a lower grade of silver than sterling.
It measures about 1 3/4 inches by 1 3/8 inches and it is in very nice condition with no visible damage.
