Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette that seems to stretch the hand with quiet elegance. This three-stone semi-set ring in 14K yellow gold offers a refined foundation for a 12 x 6 mm center stone, designed to sit low and close to the finger for everyday ease.

Crafted with precision, the setting balances secure prongs and a subtle profile that slips comfortably beneath gloves and stacks effortlessly alongside other bands. The warm glow of yellow gold complements the marquise’s tapered shape, enhancing its architectural grace without overwhelming it. Each mounting is finished by hand in our Williamsburg studio, ensuring smooth edges and a comfort fit that invites daily wear.

Our diamonds are lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

Ideal for those who appreciate a statement ring that remains practical, this design suits slender to medium finger sizes and pairs well with both vintage and contemporary styles. The semi-set format allows you to select a center diamond that matches your personal vision and budget.

Resizing is available to ensure a perfect fit, and our team is happy to guide you through care and customization options.
