Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances along the warm blush of 18K rose gold. This three-stone semi-set engagement ring invites you to select a center stone that will become the heart of a handcrafted piece, shaped by expert hands in our Williamsburg studio.

Each band is meticulously forged from 18K rose gold, its soft glow complementing the marquise’s tapered drama. The setting is designed with a low profile to sit comfortably beneath gloves or alongside other rings, while the three-stone arrangement balances visual impact with everyday wearability. Our artisans finish every curve and prong with precision, ensuring a smooth, tactile experience that feels as intimate as the moment it celebrates.

Crafted with lab-grown diamonds, this ring reflects a commitment to ethical jewelry—minimizing environmental impact without compromising brilliance or clarity.

Ideal for those who appreciate architectural elegance and a ring that molds seamlessly to daily life, this piece suits slender to medium finger sizes and pairs beautifully with stackable bands or a simple wedding band.
