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 solitaire invites you to choose a center stone that measures 9 by 4.5 millimeters, its tapered points evoking a quiet drama.

Crafted from warm 14K yellow gold, the mounting is shaped with artisan precision in our Williamsburg studio. The slender prongs curve gently to cradle the stone securely, while the band’s subtle taper balances presence with everyday comfort. Finished by hand and inspected under magnification, the setting offers a low-profile silhouette that slips easily beneath gloves or rings stacked alongside it.

Each lab-grown diamond option reflects a commitment to ethical jewelry, minimizing environmental impact without compromising brilliance or clarity.

This ring suits those who appreciate a refined statement piece that elongates the finger and pairs effortlessly with a variety of styles. Its comfort fit and modest height make it ideal for daily wear, whether alone or layered.

Should you need resizing or prefer a custom stone cut, our Brooklyn studio welcomes your vision with flexible lead times tailored to your design journey.
