Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand framed by a 10 x 5 mm marquise diamond, its tapered points softened by a delicate halo of shimmering accents. This semi-set engagement ring foundation in 14K white gold offers a low-profile silhouette designed for everyday grace and ease.

Crafted with precision in Williamsburg, the band’s smooth finish and secure prong setting ensure both comfort and durability. The halo setting enhances the marquise’s natural brilliance without adding bulk, making it glove-friendly and ideal for stacking alongside wedding bands.

Each piece is thoughtfully created using lab-grown diamonds, reflecting a commitment to sustainable and ethical jewelry practices without compromising on clarity or sparkle.

Its streamlined design suits those who appreciate architectural elegance with practical wearability—especially hands that favor slender, elongated shapes. The ring’s semi-set state invites you to select a center stone that resonates personally, allowing for a custom expression of your story.

Should resizing be needed, our Brooklyn studio offers expert adjustments to maintain the ring’s integrity and comfort.
