Lab-Grown Diamond Engagement Ring

Sunlight catches the smooth facets of an 11 mm round diamond, poised to become the centerpiece of a five-stone engagement ring that balances modern clarity with structural grace. This semi-set platinum mounting awaits your choice of lab-grown center stone, designed to showcase brilliance without distraction.

Crafted in Williamsburg, Brooklyn, the band’s low-profile setting offers a refined silhouette that sits comfortably against the finger. Each side stone is carefully positioned to enhance light play, while the platinum’s cool sheen provides a durable, hypoallergenic foundation that resists daily wear.

Our commitment to ethical jewelry is reflected in the lab-grown diamonds’ traceable origins and reduced environmental impact, marrying sustainability with sophistication.

The ring’s streamlined form suits those who appreciate confident minimalism—its comfort fit and subtle height make it ideal for stacking or everyday wear, while the round shape’s classic brilliance complements a variety of hand sizes and shapes.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a seamless fit without compromising the ring’s integrity.
