Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your finger framed by an 8 x 4 mm marquise diamond, its pointed silhouette softened by a delicate halo of shimmering accents. This semi-set engagement ring foundation in 18K white gold offers a low-profile setting designed for everyday grace and ease.

Crafted with precision in our Williamsburg studio, the band’s smooth finish and secure prong setting ensure comfort and durability without sacrificing brilliance. The halo setting enhances the marquise’s natural sparkle while maintaining a sleek profile that slips effortlessly beneath gloves or sleeves.

Our commitment to sustainability is reflected in the choice of a lab-grown diamond center, combining ethical clarity with exceptional craftsmanship. This ring suits those who appreciate architectural elegance paired with practical wearability, especially for hands that favor slender, elongated shapes.

Should you need resizing or prefer a custom consultation, our Brooklyn studio offers a pressure-free experience tailored to your lifestyle. The semi-set design invites you to select the perfect marquise stone to complete your vision.
