Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic shadow across the hand. This semi-set engagement ring invites you to select a center stone that echoes that signature tapered brilliance.

Crafted from 14K white gold, the mounting features a delicate yet secure four-prong setting designed to cradle a 12 x 6 mm marquise diamond. The band’s subtle taper and smooth finish offer a low-profile silhouette that rests comfortably for daily wear, while the artisan’s hand-polished surface reflects a quiet Brooklyn studio precision.

Each lab-grown diamond chosen for this setting carries the clarity and sparkle of natural stones with a significantly reduced environmental footprint, aligning with a mindful approach to fine jewelry.

The slender band suits slender to medium finger sizes and pairs effortlessly with wedding bands or stackable rings, thanks to its streamlined form. Its low profile also makes it glove-friendly, ideal for those who appreciate understated elegance in everyday moments.
