Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a marquise diamond catching light with every turn of the hand—its tapered points lending a quiet drama framed by a delicate halo. This semi-set engagement ring foundation invites your choice of a 10 x 5 mm marquise center, designed to sit low against the finger for everyday ease.

Crafted in 18K white gold, the mounting features a halo setting that enhances brilliance without adding bulk, while the band’s smooth finish ensures comfort beneath gloves or stacked alongside other rings. Each piece is meticulously inspected in our Williamsburg studio, where precision meets thoughtful engineering for a secure, low-profile fit.

Our commitment to lab-grown diamonds reflects a mindful approach to beauty and sustainability, offering clarity and sparkle with a lighter environmental footprint.

Ideal for those who appreciate architectural elegance paired with practical wearability, this ring balances statement and subtlety, making it a versatile choice for daily life and special moments alike.
