Simply Round Diamond Engagement Ring 2678The Simply Tacori 2678RD was built around restraint. A slim 18k yellow gold band tapers to a cathedral foundation where crescent silhouette windows and diamond accented prongs carry 0. 18 carats of G, VS detail at the crown, with milgrain and the Simply Tacori crescent inner face finishing what the band deliberately leaves open. The kind of engagement ring someone chooses because subtlety was never a compromise.
