Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, luminous shadow that dances across your hand. This 7 x 3.5 mm marquise center stone is embraced by a delicate halo of pavé-set lab-grown diamonds, amplifying its tapered drama with a subtle sparkle.

Crafted from warm 14K rose gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit, designed for everyday wear without catching or discomfort. The low-profile halo setting balances brilliance with practicality, allowing the ring to nestle easily alongside wedding bands or stackable favorites.

Each diamond is ethically sourced from our lab-grown collection, ensuring clarity and sustainability without compromise. The rose gold’s soft blush tone complements the marquise’s vintage-inspired shape, making it an elegant choice for those drawn to refined yet distinctive design.

This ring suits hands that appreciate sculptural lines and a touch of romantic edge, especially flattering on slender fingers where the marquise shape elongates and refines. Its secure setting and durable finish make it a confident daily companion.

Should you need a custom size, resizing is available with careful attention to preserving the ring’s structural integrity and finish. Typical lead times reflect our artisan process, ensuring each piece meets exacting standards.
