Lab-Grown Diamond Engagement Ring

Sunlight catches the delicate facets of a 3 mm round diamond, casting a quiet sparkle that feels like a whispered promise. This semi-set solitaire ring invites you to choose a center stone that reflects your unique story, framed by an 18K white gold band with a soft, warm glow from its rose gold interior.

Crafted with precision in Williamsburg, Brooklyn, the band’s slender profile and smooth finish ensure a comfortable fit for everyday wear. The low-profile setting keeps the diamond close to the hand, making it ideal for stacking or pairing with a wedding band without interruption.

Each ring is thoughtfully designed with lab-grown diamonds, offering clarity and brilliance while honoring a commitment to sustainable, ethical jewelry practices. The gentle contrast of white and rose gold adds subtle depth without overwhelming the stone’s natural fire.

Perfect for those who appreciate understated elegance and a ring that adapts to daily life, this solitaire setting complements a variety of diamond shapes and sizes beyond the 3 mm round, allowing for a truly personalized expression.

Should you wish to adjust the band size or explore custom finishes, our Brooklyn studio offers attentive care and expert guidance throughout the process.
