Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This semi-set solitaire ring invites you to select a 10 x 5 mm center stone, its distinctive shape evoking a refined, tapered drama that elongates the finger with subtle elegance.

Crafted from warm 14K rose gold, the band is shaped and finished in our Williamsburg studio with a smooth, comfort fit that feels natural for daily wear. The low-profile setting keeps the diamond close to the hand, balancing presence with practicality, while the artisan’s hand-polished finish ensures a soft glow that complements the stone’s brilliance.

Each lab-grown diamond offers a clear, sustainable alternative, reflecting our commitment to ethical jewelry without compromise on beauty or quality.

This ring suits those who appreciate a bold yet refined silhouette, perfect for stacking with slender bands or worn solo to highlight the marquise’s architectural allure. Its design accommodates resizing and is glove-friendly, ideal for an active lifestyle.
