Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette across the hand. This semi-set solitaire ring in 18K yellow gold awaits your choice of a 7 x 3.5 mm center stone, offering a refined foundation for a distinctive engagement piece.

Crafted with a low-profile setting, the band sits close to the finger for everyday comfort and ease beneath gloves or alongside other rings. The warm glow of 18K yellow gold is hand-finished in our Williamsburg studio, ensuring smooth edges and a subtle polish that enhances wearability without excess shine.

Each diamond is lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

This design suits those who appreciate architectural elegance paired with practical design—ideal for slender fingers or anyone seeking a ring that balances statement with subtlety. Its streamlined silhouette makes it easy to stack or wear solo with quiet confidence.

Resizing is available to ensure a perfect fit, and our studio can guide you through selecting a center stone that complements this mounting’s proportions.
