Product Highlights
The Perfect Centerpiece: Features a hand-selected radiant cut lab-grown diamond, celebrated for combining the elegant silhouette of an emerald cut with the intense fire of a round brilliant. The "crushed ice" sparkle of the radiant cut makes it a standout choice for maximum light performance.

Unique Double-Prong Craftsmanship: The center stone is meticulously secured by specialized double prongs at each corner. This unique design choice not only provides enhanced security for the diamond but also adds a modern, custom-jewelry aesthetic to the pendant’s profile.

Diamond-Set Decorative Hook: The pendant is suspended from a sophisticated hook delicately studded with round lab-grown melee diamonds (0.10 TCW), ensuring a touch of brilliance that leads the eye directly to the center stone.
