Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated silhouette of a marquise diamond, it casts a slender, dramatic sparkle that draws the eye along the finger’s natural line. This semi-set engagement ring foundation in 10K yellow gold is crafted to showcase a 12 x 6 mm marquise center stone, framed by delicate accent settings that enhance brilliance without bulk.

The band is designed with a low-profile setting to sit comfortably beneath gloves or daily wear, while the smooth finish ensures a gentle feel against the skin. Each piece is meticulously hand-finished in our Williamsburg studio, where precision meets understated strength for everyday elegance.

Our diamonds are lab-grown, offering a clear, sustainable choice that reflects a modern commitment to ethical jewelry without compromising on radiance.

This ring suits those who appreciate architectural grace paired with practical design—its slender shape elongates the hand, and the semi-set style invites you to select a center stone that fits your vision. The secure setting and balanced weight make it ideal for stacking or solo wear.

Resizing is available to ensure a perfect fit, crafted with care to maintain the ring’s sleek profile and structural integrity.
