Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a subtle, tapered glow that draws the eye along the finger’s natural line. This semi-set halo engagement ring in 18K yellow gold frames a 7 x 3.5 mm marquise center with a delicate circle of pavé stones, enhancing brilliance without adding bulk.

Crafted for everyday wear, the low-profile setting keeps the silhouette close to the hand, reducing snag risk while maintaining a refined presence. The warm gold band is smoothly finished with a comfort fit, balancing durability with a gentle touch against the skin. Each piece is meticulously inspected in our Williamsburg studio to ensure precision and lasting quality.

Our lab-grown diamonds offer a clear, sustainable alternative, reflecting a commitment to ethical jewelry without compromise on sparkle or structure.

Designed for those who appreciate a sleek, architectural shape paired with a halo’s soft radiance, this ring complements slender fingers and layers effortlessly with other bands. Its modest height makes it glove-friendly and ideal for daily life.

Should you need resizing, our Brooklyn studio provides expert adjustments to ensure a perfect fit without altering the ring’s integrity.
