Certificates
Handcrafted in New York by Ring Premier's master jewelers. The Geneva four-prong basket is the most widely used setting in diamond studs — four prongs grip the stone at the crown, the open gallery underneath lets light through the pavilion, and the symmetry favors face-up generous round brilliants. PT950 Platinum is 95% pure platinum — the densest and most naturally white precious metal, requiring no plating and developing a distinctive patina over time.
Ring Premier exclusively uses recycled precious metals and conflict-free, lab-grown stones. All lab-grown diamonds are verified as 100% carbon neutral by Clear Neutral. Each earring undergoes multi-stage quality inspection — including prong tightness testing, girdle alignment verification, and a final loupe inspection under 10× magnification — before shipping.
