The oval CZ in a bezel setting is one of the cleaner expressions of the modern solitaire stud: the stone's elongated shape reads as more current than a round, and the bezel setting wraps it in a continuous metal collar that keeps the profile low and architectural. In 14K gold over sterling silver with butterfly back. No prongs to snag, no raised elements to catch - just the stone and the metal in clean relationship. The oval format also has a subtle elongating effect at the ear, which is one of the reasons it has become the preferred solitaire shape for fashion-aware jewelry wearers. A straightforward piece executed well.
