Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic sparkle that draws the eye along the finger’s natural line. This semi-set solitaire ring invites you to select a center stone that measures 10 by 5 millimeters, a size that balances bold presence with everyday grace.

Crafted from 18K white gold, the mounting is shaped with a delicate yet sturdy bezel that cradles the stone securely while maintaining a low profile for comfortable daily wear. The band’s smooth finish and subtle tapering ensure it feels light and natural against the skin, ideal for stacking or wearing solo.

Each piece is meticulously hand-finished in our Williamsburg studio, where artisan techniques meet modern precision. The setting’s clean lines and refined edges reflect a commitment to craftsmanship that honors both form and function.

Our lab-grown diamonds offer a clarity and brilliance that rival mined stones, created with a smaller environmental footprint and traceable origins, aligning with a mindful approach to fine jewelry.

This solitaire suits those who appreciate architectural elegance and a ring that complements an active lifestyle without sacrificing style. Its slender shape elongates the finger, while the secure setting makes it glove-friendly and resilient.
