Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a delicate shimmer that seems to stretch beyond the finger. This semi-set solitaire invites you to choose a center stone that echoes your unique story, framed by an 18K yellow gold band that warms the skin with its subtle glow.

Crafted in Williamsburg, the band’s slender profile balances elegance with everyday wearability, its smooth finish designed for comfort and ease beneath gloves or alongside stackable rings. The low-profile setting keeps the diamond close to the hand, minimizing snagging while maximizing the stone’s signature tapered drama.

Each piece reflects a commitment to sustainability through lab-grown diamonds, offering clarity and brilliance without compromise. The marquise shape, with its pointed ends and graceful curve, elongates the finger and lends a refined, architectural charm that suits those drawn to distinctive yet understated design.
