Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of a marquise diamond, casting a slender beam that seems to stretch beyond the finger. This semi-set solitaire invites you to choose a 5 x 3 mm marquise stone, its pointed silhouette evoking a quiet elegance and subtle drama.

Crafted in warm 14K rose gold, the mounting’s delicate prongs cradle the stone with precision, while the slender band offers a gentle comfort fit that feels natural for everyday wear. The low-profile setting keeps the ring close to the hand, making it glove-friendly and ideal for stacking alongside other bands.

Each piece is finished by hand in our Williamsburg studio, where careful inspection ensures the smooth polish and secure setting that define our craftsmanship. The rose gold’s soft blush complements the marquise’s vintage-inspired shape, creating a romantic harmony of form and color.

Our commitment to ethical jewelry shines through the choice of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint. This ring suits those who appreciate refined silhouettes and a design that balances statement with subtlety.
