Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances along the finger. This semi-set solitaire invites you to choose a center stone that measures 12 by 6 millimeters, its tapered points lending a graceful drama to the hand.

Crafted from warm 14K rose gold, this mounting is shaped with a refined artisan’s touch—smooth edges and a subtle curve ensure comfort for daily wear. The low-profile setting balances presence with practicality, allowing the diamond to sit close to the skin without catching on fabric.

Each ring is finished by hand in our Williamsburg studio, where precision meets quiet elegance. The rose gold’s soft glow complements the marquise’s vintage-inspired geometry, while the sturdy prongs secure your chosen stone with care.

Our commitment to ethical jewelry is reflected in the lab-grown diamonds you select—offering clarity and brilliance with a smaller environmental footprint.

Designed for those who appreciate a statement that is both bold and wearable, this solitaire suits slender to medium finger shapes and layers effortlessly with wedding bands or stackable rings. Its comfort fit and modest height make it glove-friendly and ideal for everyday life.
