Crafted in your choice of solid 9K, 14K or 18K gold, or platinum—never gold-plated silver or base metal. Every piece is hand-set by our master setters and finished through a multi-stage polish. Before anything leaves our atelier, it passes inspection under 30x magnification — prong security, stone alignment, surface finish.
Video walkthrough: once your piece is complete, we send you a detailed video of your actual ring so you can verify every detail before it ships.
Certificate match: For individually IGI-certified diamonds, we match the stone's laser inscription to its grading report before tracked DHL/FedEx dispatch. Smaller pavé and accent diamonds are not individually certified unless expressly stated.
