Bvlgari B.ZERO1 Ring 18k Rose Gold & Ceramic Authentic, paid over $2,000 for it at the Bvlgari boutique. Gifted to girlfriend, things didn't work out, so now I have it. Inside ring shows size is 51, 18k rose gold (Au 750), and made in Italy. I know it's tiny in the photos but they're there. Never been polished or retouched after purchasing. No box or papers, just selling the ring.
