Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your finger as an 8 x 4 mm marquise diamond begins its quiet dance with light—tapered points catching every glance. This semi-set engagement ring foundation in 14K white gold offers a sleek, low-profile silhouette designed for everyday grace without compromise.

Crafted in Williamsburg, the band’s smooth finish and secure prong arrangement ensure comfort and durability, ideal for a life lived fully. The mounting invites your choice of a marquise center stone, celebrated for its elegant, tapered drama that visually lengthens the hand.

Each piece reflects our commitment to ethical jewelry through lab-grown diamonds, reducing environmental impact while maintaining exceptional clarity and brilliance. The ring’s modest height and balanced proportions make it glove-friendly and stackable with other bands, fitting seamlessly into varied lifestyles.

Should you need resizing, our Brooklyn studio offers precise adjustments to maintain the ring’s integrity and comfort. Lead times are transparent and tailored to your custom design journey.
