Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a marquise diamond catching light with every turn of the hand—its pointed ends lending a refined silhouette that feels both bold and elegant.

This semi-set engagement ring features an 18K white gold band crafted for a low-profile fit, designed to sit comfortably beneath gloves or daily wear. The mounting awaits your choice of a 10 x 5 mm marquise center, framed by delicate accent stones that enhance its sculptural presence without overwhelming.

Each piece is meticulously finished in our Williamsburg studio, where expert hands polish and inspect every curve to ensure a seamless, secure setting that balances durability with refined craftsmanship.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint.

The slender band suits those who appreciate a sleek, modern aesthetic—ideal for stacking or wearing solo with ease. Its low profile makes it a practical choice for active lifestyles without sacrificing visual impact.

Should you need resizing, our in-studio team provides precise adjustments to ensure a perfect fit without compromising the ring’s integrity.
