Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 5 x 5 mm cushion diamond, its gentle glow framed by two smaller stones that balance warmth with quiet brilliance. This three-stone semi-set ring invites you to choose a center diamond that speaks to your story, resting in a 10K white gold band shaped for everyday grace.

Each band is meticulously crafted in our Williamsburg studio, where the cool luster of white gold is hand-finished to a smooth comfort fit. The low-profile setting keeps the stones close to the hand, making it easy to wear alone or stacked with other favorites. The prongs curve delicately, securing your stones while allowing light to dance freely across each facet.

Our commitment to lab-grown diamonds means your ring carries a clarity and brilliance born from sustainable innovation, reflecting a modern approach to ethical jewelry.

Designed for those who appreciate subtle elegance and artisanal detail, this ring suits a variety of hand shapes and sizes, its cushion cut elongating the finger with a soft vintage glow. The three-stone layout offers a narrative of past, present, and future, perfect for marking meaningful moments.
