Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc that seems to stretch the fingers with quiet elegance. This semi-set solitaire ring invites you to select a center stone measuring approximately 9 by 4.5 millimeters, showcasing the marquise’s signature tapered points and brilliant facets.

Crafted from 18K white gold, the mounting is shaped with a refined low-profile setting that balances security with subtlety. The band’s smooth finish and gentle curvature offer a comfortable fit for daily wear, while the artisan hands in our Williamsburg studio inspect each detail to ensure flawless craftsmanship.

Our commitment to lab-grown diamonds means this ring carries a clear ethical edge—offering the same optical brilliance as mined stones with a lighter environmental footprint.

Designed for those who appreciate a statement piece that remains understated in its wearability, this solitaire suits slender to medium finger sizes and pairs effortlessly with wedding bands or stackable rings. Its low profile also makes it glove-friendly and ideal for an active lifestyle.

Should you wish to adjust the band size or explore custom finishes, our Brooklyn studio welcomes consultations to tailor your ring precisely.
