Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This three-stone semi-set ring features a 9 x 4.5 mm marquise center, poised to be paired with your choice of side stones for a personalized narrative.

Crafted from 14K white gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit, designed for daily wear without catching or discomfort. The low-profile setting balances presence with practicality, allowing the marquise’s signature brilliance to shine while maintaining a sleek profile.

Each ring is finished by hand, inspected under magnification to ensure precision in every prong and contour. Our artisan approach honors the geometry of the marquise cut, emphasizing its graceful elongation and vintage-inspired allure.

Ethically sourced, the lab-grown diamond offers clarity and sparkle with a reduced environmental footprint, reflecting a commitment to sustainable luxury.

This design suits those who appreciate a refined statement that complements slender or average finger shapes, and its semi-set nature invites you to customize side stones that echo your personal style. The band’s smooth interior and modest height make it glove-friendly and stackable with wedding bands or accent rings.

Should you need resizing or guidance on selecting side stones, our Brooklyn studio team is ready to assist with care and expertise.
