Lab-Grown Diamond Engagement Ring

Under the soft glow of Williamsburg’s evening light, the sharp geometry of an 8 x 8 mm Asscher diamond begins to reveal its architectural depth. This semi-set three-stone ring foundation in 18K white gold invites your choice of center stone, framed by two delicate side settings that catch the light with subtle precision.

Crafted in our Brooklyn studio, the band’s smooth comfort fit and low-profile setting ensure it sits close to the finger, ideal for daily wear without catching. Each curve and angle is hand-finished to a satin polish, reflecting the quiet rigor of artisan workshop techniques.

Our commitment to lab-grown diamonds means this ring supports ethical jewelry values with clarity and sustainability at its core.

The clean lines of the Asscher cut—its step facets and square silhouette—offer a modern yet vintage-inspired elegance, perfect for those who appreciate architectural form and refined understatement. The three-stone layout balances presence with wearability, suitable for stacking or solo wear.

Should you need resizing, our in-house experts adjust the band with care to maintain its integrity and comfort.
