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 invites you to select a center stone that balances architectural drama with refined elegance.

Crafted in warm 14K rose gold, the mounting features a low-profile setting designed for everyday wear. The band’s subtle curve and secure prongs ensure comfort and durability without excess height, making it glove-friendly and stackable with other bands. Each piece is hand-finished in our Williamsburg studio, where precision meets quiet craftsmanship.

Our diamonds are lab-grown, offering clarity and brilliance with a smaller environmental footprint. This ethical choice aligns with a modern approach to fine jewelry, marrying beauty with responsibility.

The 6 x 3.5 mm marquise shape elongates the finger, lending a sleek silhouette that suits those who appreciate clean lines and understated sophistication. Its versatile size pairs well with both delicate and bold styles.

Should you need resizing or prefer a custom stone, our in-studio team is ready to guide you through the process with care and expertise.
