Though these deco inspired earrings by Angelique de Paris say”vintage jade” in their name, impossible to know what they are actually made of as the site provides exactly zero details. They sure are pretty though (and would go great with yesterday’s emerald and diamond ring).
Green/diamond/black was a common colour way in Art Deco jewelry, so this is perfectly in keeping with that vibe, and the discs could well be actual jade – or they could be glass or plastic. Contact the company if more details are required (as they no doubt would be before purchasing, caveat emptor, etc.) These sell for USD$249.
