Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a delicate 18K rose gold band. This semi-set three-stone engagement ring invites your choice of center stone, framing it with two smaller companions that enhance its graceful drama.

Handcrafted in our Williamsburg studio, the band’s warm rose gold is carefully shaped for a comfortable fit, its subtle curve designed to sit low against the finger for everyday wear. The prong setting balances security with light exposure, allowing the marquise’s signature brilliance to unfold without interruption.

Each diamond here is lab-grown, reflecting a commitment to sustainable luxury and traceable origins without compromise on clarity or fire.

Ideal for those who appreciate a refined statement with vintage-inspired geometry, this ring complements slender fingers and pairs beautifully with stackable bands or a simple wedding band. Its low-profile setting ensures it slips easily under gloves or sleeves, making it a practical choice for daily life.
