Vintage high relief bangle bracelet

Vintage high relief bangle bracelet. Very fine detailing. It is a plated piece, but I can not confirm what the base metal is…my guess is plated brass. May be a genuine light amethyst? But I am not sure of that…makes sense for the time period though. My guess is late 19th c ? High quality piece regardless of details. Just over 2” top to bottom 2.75” approx. side to side.
