Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise, its pointed ends tracing a delicate arc that seems to stretch the hand with quiet elegance. This five-stone semi-set ring in 10K white gold offers a refined foundation for a 12 x 6 mm marquise center, its shape lending a subtle drama without overwhelming daily wear.

Crafted with a low-profile setting, the band’s gentle curve and polished finish ensure comfort and ease beneath gloves or alongside stackable favorites. Each prong is meticulously shaped to cradle the stone securely while allowing maximum light to animate the facets, a hallmark of our Brooklyn studio’s attention to detail.

Our lab-grown diamonds provide clarity and brilliance with a mindful footprint, reflecting a commitment to ethical jewelry without compromise. The cool white gold complements the marquise’s glassy elongation, creating a modern yet intimate statement.

Ideal for those who appreciate a blend of architectural grace and romantic subtlety, this ring balances presence with wearability, fitting hands that favor slender, elongated forms or those seeking a distinctive centerpiece for layering.
