Lab-Grown Diamond Engagement Ring

Imagine the quiet moment when a heart-shaped diamond catches the light just so—its soft curves and pointed tip reflecting a personal promise. This solitaire semi-set invites you to choose a 10 x 10 mm heart-shaped center stone, a shape that balances romantic symbolism with a distinctive silhouette.

Crafted in warm 18K yellow gold, the mounting is designed with a low-profile setting that sits close to the finger, ensuring comfort for everyday wear. The band’s smooth finish and subtle taper allow the diamond to take center stage without distraction, while the secure prongs cradle the stone with precision. Each piece is meticulously inspected in our Williamsburg studio to meet exacting standards of craftsmanship.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint.

This ring suits those who appreciate a blend of classic romance and modern practicality—its comfort fit and modest height make it ideal for stacking or wearing solo, and its balanced proportions flatter a range of hand sizes.

Should you need resizing or prefer a custom stone selection, our Brooklyn studio offers personalized consultations to guide you through every detail with care and expertise.
