Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand as a 10 x 5 mm marquise diamond catches the light, its tapered points drawing the eye with quiet drama. This semi-set solitaire ring in 10K white gold offers a sleek, low-profile mounting designed for everyday grace and resilience.

Crafted in Williamsburg, the band’s smooth comfort fit and secure prong setting ensure the diamond sits close to the finger, minimizing snagging while maximizing sparkle. The polished finish reflects the studio’s exacting standards, inspected meticulously before it leaves the bench.

Each lab-grown diamond embodies a commitment to ethical sourcing and sustainability, marrying beauty with responsibility.

Ideal for those who appreciate architectural elegance with practical wearability, this solitaire pairs effortlessly with stackable bands or stands alone as a statement of refined taste. Its slender silhouette suits a range of finger shapes, offering a balanced feel without bulk.
