Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 9x9 mm cushion diamond, its gentle glow framed by two smaller stones that balance modern geometry with quiet elegance. This three-stone semi-set ring invites you to select a center diamond that reflects your personal story, resting in an 18K white gold band crafted for subtle strength and refined clarity.

Each band is meticulously shaped and polished in our Williamsburg studio, offering a low-profile silhouette that sits comfortably for daily wear. The clean lines and structured setting emphasize the cushion’s vintage-inspired softness while maintaining a contemporary minimalism that feels deliberate, not decorative.

Our commitment to lab-grown diamonds ensures a clarity and brilliance born from sustainable practices, reducing environmental impact without compromising on sparkle.

Designed for those who appreciate architectural balance and understated confidence, this ring pairs effortlessly with stackable bands or stands alone as a statement of intention. Its comfort fit and moderate profile make it glove-friendly and ideal for everyday life.
