Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 9 mm round diamond, poised to become the heart of a three-stone engagement ring. This semi-set foundation, crafted from warm 18K yellow gold, awaits your choice of center stone to complete its artisan composition.

Each band is hand-shaped in our Williamsburg studio, with a subtle taper that balances the three-stone arrangement while maintaining a comfortable, low-profile fit. The polished finish enhances the metal’s natural glow, designed for daily wear without compromising elegance.

Our commitment to sustainability is reflected in the lab-grown diamond clarity this ring embraces—ethical jewelry that honors both beauty and responsibility.

The three-stone style suits those who appreciate symbolic layers of meaning and visual depth, while the 18K yellow gold band offers a warm contrast to the diamond’s brilliance. Its gentle curve and moderate width make it ideal for stacking or wearing solo, fitting comfortably beneath gloves or rings alike.

Should you need resizing, our Brooklyn studio provides precise adjustments to ensure a perfect fit without disrupting the ring’s balance.
