Real Amethyst & diamond ring

Bought this ring 3 years ago for my 16th birthday. It was too fancy for me to wear at a young age and now I just find that I never wear it and would rather sell it to get something I would wear. I bought the ring for around $800 at E. B. horn jewelers in Boston MA. I only wore this ring once, PRISTINE condition. No flaws and no scratches. Real amethyst stone with diamond halo. I also think at $500 Poshmark authenticates it as well. Gorgeous! Size 7.5 Tagged David yurman for exposure
