Product Highlights
Regal Marquise Silhouette: A breathtaking "river of light" featuring marquise cut lab-grown diamonds. The elongated shape of each 5.00 x 2.50 mm stone creates a high-fashion, high-impact aesthetic that offers a unique and sharp alternative to traditional round strands.

Minimalist 2-Prong Setting: Each marquise diamond is meticulously secured by specialized two-prong settings at the tips. This design maximizes the diamond's surface area, allowing light to flood the stones from all angles while maintaining a sleek, modern profile.

Jewel Nests "No-Flip" Engineering: Our precision-linked settings are specially designed to sit flat against the collarbone. This no-flip construction is a Jewel Nests special, ensuring your necklace stays perfectly in place without twisting or turning.

Secure Box Clasp Lock: Equipped with a high-security integrated box clasp and safety latches, ensuring your luxury necklace stays safely fastened through every movement.
