Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 7x7 mm cushion diamond, its gentle glow framed by two smaller stones that balance modern clarity with quiet strength. This three-stone semi-set ring offers a structured silhouette, crafted in 10K white gold with a refined low-profile setting that sits close to the finger for everyday ease.

Each band is hand-finished in our Williamsburg studio, polished to a satin-smooth touch that complements the geometric precision of the cushion cut. The semi-set design invites you to select a center stone that reflects your personal story, while the secure prong setting ensures lasting wearability without bulk.

Our diamonds are lab-grown, embodying a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

Ideal for those who appreciate minimalist design with architectural lines, this ring fits comfortably beneath gloves and stacks seamlessly alongside wedding bands or delicate accessories. Its balanced proportions flatter a range of hand shapes, especially elongating shorter fingers with the cushion’s soft, vintage-inspired glow.
