Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 10 x 10 mm cushion diamond, its gentle glow balanced by two smaller side stones in a three-stone embrace. This semi-set engagement ring foundation invites your choice of center stone, resting on a warm 14K yellow gold band that feels substantial yet refined against the skin.

Handcrafted in our Williamsburg studio, the band’s smooth finish and low-profile setting ensure everyday comfort without sacrificing presence. The three-stone design is carefully calibrated for balance, allowing light to dance freely across each facet while maintaining a secure, elegant hold.

Each lab-grown diamond offers clarity and brilliance with a smaller environmental footprint, reflecting a commitment to ethical jewelry that honors both beauty and responsibility.

Ideal for those who appreciate classic forms with a modern sensibility, this ring suits a variety of hand shapes and sizes, its modest height making it glove-friendly and stackable alongside wedding bands or personal treasures.

Should you wish to adjust the fit, resizing is available through our in-studio service, ensuring your ring feels as natural as it looks.
