Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light like a shard of morning sun. This semi-set three-stone engagement ring offers a poised foundation for a 12 x 6 mm center stone, designed to frame the gem with balanced elegance.

Crafted from polished platinum, the mounting features a low-profile setting that sits comfortably against the finger, with securely sculpted prongs that showcase the marquise’s tapered points without overwhelming its refined geometry. Each element is hand-finished in our Williamsburg studio, where precision meets artisan care to ensure a smooth, comfort-fit band that wears effortlessly every day.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and brilliance with a reduced environmental footprint.

The slender silhouette of the marquise shape naturally elongates the hand, while the three-stone design adds a narrative depth—ideal for those who appreciate a blend of classic form and contemporary craftsmanship. Its modest profile makes it glove-friendly and suitable for stacking with other bands.

Should you need resizing, our in-house team adjusts each ring with meticulous attention to preserve its structural integrity and finish.
