Classic 4 Prong Princess Cut Ethical Lab Diamond Pendant Necklace

Expertly finished in mirror-polished platinum, this timeless pendant necklace centers a crisp princess-cut ethical lab diamond locked in a sleek four-prong solitaire mount. Built with a refined dual-layer open gallery structure underneath the stone, the hollow layered cutouts remove excess metal to boost light flow through every sharp facet, amplifying the gem’s brilliant fire while keeping the piece lightweight. The slim polished platinum chain offers smooth comfortable wear against the collarbone. Minimalist, durable and ethically sourced, it fits daily styling, formal occasions and anniversary gifting, a sophisticated heirloom-worthy fine jewelry staple with enduring classic charm.
