Beautiful Enameled with Green Cabochon Hinged Bangle

Vintage unbranded light green enameled design around a beautiful hinged bangle containing 18 round dark green cabochon stones, all outlined with a brownish, maroon enameled edge with each part of the design outlined with what looks to be brass or similar metal. This bracelet is held closed with a very strong magnet, making its ability to fall off difficult. And pretty substantial in weight.
