Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the length of the finger with quiet drama. This semi-set solitaire ring foundation in warm 10K yellow gold awaits your choice of a 9 x 4.5 mm marquise stone, ready to frame its distinctive shape with artisan precision.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a subtle taper that balances presence and wearability. The low-profile setting ensures daily ease, while the polished finish reflects light softly, complementing the diamond’s glassy, tapered brilliance. Each mounting is meticulously inspected to meet exacting standards before it leaves the bench.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and sustainability without compromise. The slender band suits those who appreciate refined geometry and a ring that layers effortlessly with wedding bands or stackable designs.
