This bangle looks to be made of etched brass but I'm not positive. In the center is a pink shell cameo and on either side is an angel skin coral which I think is an interesting combination. All three are prong set and are surrounded by hollow tiny circle frames. The cameo measures 7/8" X 1/2" without the border and the angel skin coral pieces measure 1/2" X 3/8". The width of the bangle is 1/2". The inside circumference is 7". The tab in slot closure works well and is secure. There are some tiny black marks on the cameo that I have since rubbed off with my finger. No chips or cracks on the cameo or coral stones.
