Lab-Grown Diamond Engagement Ring

Sunlight catches the slender marquise diamond’s pointed tips, casting a delicate sparkle that seems to stretch beyond the finger’s curve. This semi-set solitaire invites your choice of a 6 x 3 mm lab-grown marquise, a shape known for its graceful elongation and subtle drama.

Crafted in warm 10K yellow gold, the mounting’s slender prongs cradle the stone with precision, allowing light to flood the facets while maintaining a secure hold. The band’s gentle taper and smooth finish ensure a comfortable, everyday wear that slips easily beneath gloves or stacks with other bands.

Each piece is hand-finished in our Williamsburg studio, where attention to detail meets a quiet dedication to quality. The low-profile setting balances presence with practicality, designed to live seamlessly with your daily rhythm.

Our lab-grown diamonds offer a clarity and brilliance equal to mined stones, with a fraction of the environmental impact—an ethical choice that speaks softly but clearly.

This solitaire suits those who appreciate refined geometry and understated elegance, especially flattering on slender fingers or as a centerpiece for a custom design. Resizing is available to ensure a perfect fit, crafted to your hand’s unique shape.
