This is a very lovely domed onyx brooch with an amazing shine on the front and unfinished in the back. Please note that because the top of the stone is so reflective, the photo picks up everything (including me taking the photo). My best photo was taken in a closet without a flash! See the lengths I will go to to provide good photos :)
The brooch measures 1 3/4" in diameter. The frame is unmarked. It may be sterling; when I rub it with the polishing cloth it leaves a dark mark, but the patina is so nice on it I wouldn't polish it.
The trombone clasp works well and the pin itself is sharp. The tip of the trombone clasp has a tiny flower design on it!
The pin is heavy and would work best on a coat or jacket. Simply stunning!
There is a small notch in the onyx that is visible from the back, but not noticeable from the front. Please see photo.
