Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it casts a striking, tapered brilliance that draws the eye along the finger’s natural line. This semi-set engagement ring foundation in 18K white gold offers a refined stage for an 8 x 4 mm marquise center, framed by delicate accent stones that enhance its sculptural presence without overpowering.

Each band is meticulously crafted in our Williamsburg studio, where the cool sheen of white gold is hand-polished to a satin finish that feels smooth against the skin. The low-profile setting balances elegance with everyday wearability, designed to slip comfortably beneath gloves or stack alongside other bands with ease.

Our commitment to ethical jewelry is reflected in the choice of lab-grown diamonds, offering clarity and sparkle with a significantly reduced environmental footprint.

This ring suits those who appreciate architectural grace paired with subtle artisan detail—ideal for slender fingers or anyone seeking a statement piece that remains understated in daily life.
