Lab-Grown Diamond Engagement Ring

Imagine the gentle curve of a marquise diamond catching the light as it elongates the finger with quiet elegance. This semi-set solitaire ring awaits your choice of a 10 x 5 mm marquise stone, its pointed ends lending a subtle drama that feels both refined and intimate.

Crafted in 18K white gold, the mounting features a delicate yet secure setting designed to cradle the stone with minimal metal visible, allowing brilliance to take center stage. The band’s slender profile and smooth finish ensure a comfortable fit for everyday wear, while the low-profile design keeps it glove-friendly and easy to stack with complementary bands.

Each piece is thoughtfully made in our Williamsburg studio, where expert hands polish and inspect every detail to meet exacting standards. Our commitment to lab-grown diamonds means your ring carries a clarity and sparkle born from sustainable innovation, reflecting a modern approach to ethical jewelry.

This solitaire suits those who appreciate a blend of classic form and contemporary conscience—ideal for hands that favor elegance without excess. The semi-set nature invites you to select a marquise stone that resonates personally, making the ring uniquely yours.
