Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of the 9 x 7 mm oval diamond, casting a soft glow that stretches gracefully across the finger. This three-stone engagement ring balances modern minimalism with architectural clarity, its clean lines emphasizing the stone’s natural brilliance.

Crafted in polished platinum, the setting offers a low-profile silhouette that rests comfortably against the skin. Each diamond is securely nestled in a precise prong setting, allowing light to dance freely while maintaining everyday wearability. The band’s subtle weight and smooth finish reflect careful hand-finishing and rigorous inspection in our Williamsburg studio.

Choosing a lab-grown diamond ensures a transparent origin and a smaller environmental footprint, aligning with a thoughtful approach to ethical jewelry.

Designed for those who appreciate refined structure and confident simplicity, this ring pairs effortlessly with other stackable bands or stands strikingly alone. Its low profile makes it glove-friendly and ideal for daily wear without sacrificing presence.

Should you need a custom fit, resizing is available to ensure the ring feels as natural as it looks.
