Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow across the hand. This semi-set solitaire invites you to select a center stone that echoes your unique story, framed by a warm 14K rose gold band that feels both intimate and enduring.

Handcrafted in our Williamsburg studio, the band is shaped with a subtle comfort fit, its smooth interior contouring gently beneath the finger. The low-profile setting is designed to cradle the marquise securely while maintaining a sleek profile that slips easily under gloves or alongside stackable rings. Each curve and angle is refined through artisan techniques, ensuring a polished finish that catches light without excess.

Our commitment to ethical jewelry shines through the choice of lab-grown diamonds, offering clarity and brilliance with a reduced environmental footprint.

This ring suits those who appreciate architectural elegance paired with everyday wearability—its elongated marquise shape visually lengthens the finger, while the rose gold adds a soft, modern warmth. Whether worn solo or layered, it balances boldness with subtlety.

Should you wish to adjust the band size, resizing is available to ensure a comfortable, lasting fit.
