Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, graceful shadow across the hand. This semi-set engagement ring invites you to select a 12 x 6 mm marquise stone, whose tapered points and brilliant facets evoke a refined drama.

Crafted from 14K white gold, the mounting features delicate accent stones that frame the center with subtle sparkle. The artisan’s touch is evident in the smooth, low-profile setting designed for everyday wear, balancing elegance with comfort. Each curve is hand-finished in our Williamsburg studio, ensuring a flawless fit and a polished surface that catches light with quiet sophistication.

Our commitment to sustainability shines through the choice of lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint.

The slender band suits those who appreciate a ring that feels light and unobtrusive, ideal for stacking or wearing alongside a wedding band. Its low profile makes it glove-friendly and practical for daily life without sacrificing style.
