High karat gold vermeil black stone silver bangle

This is a gorgeous bangle made with a black stone and high karat gold vermeil on 925 silver. Vermeil is a thick layer of gold plating over sterling silver. I don’t know what the black stone is. It could be black coral, jade or onyx. It’s inner diameter is 2 3/8 inches, so it will best fit a wrist size 7.0-7.5 inches. Stamped 925 on the clasp. In excellent vintage condition.
