Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, its tapered points drawing the eye along the finger with quiet drama. This semi-set halo engagement ring foundation in 18K rose gold offers a delicate warmth beneath the stone, crafted to sit low and close for everyday grace.

Hand-finished in our Williamsburg studio, the band’s smooth contour ensures a comfort fit that resists catching, while the halo setting is designed to amplify brilliance without adding bulk. The rose gold’s subtle blush complements the marquise’s sharp geometry, balancing architectural edge with soft wearability.

Each lab-grown diamond is chosen for clarity and ethical provenance, reflecting a commitment to sustainability without compromise. The semi-set design invites you to select an 8 x 4 mm marquise center stone that suits your vision, with expert guidance available to ensure a seamless fit.

Ideal for those who appreciate a refined profile and a ring that layers effortlessly with other bands or stands alone with quiet confidence. Its low profile makes it glove-friendly and suited for daily life, marrying Brooklyn craftsmanship with modern practicality.
