Lab-Grown Diamond Engagement Ring

Light catches the slender points of a marquise diamond, casting a subtle, elongated sparkle that draws the eye along the finger’s natural curve. This semi-set engagement ring foundation in 10K white gold offers a refined stage for a 9 x 4.5 mm marquise center stone, framed by delicate accent settings that enhance its sculptural silhouette.

Each band is hand-shaped and polished in our Williamsburg studio, with a low-profile setting designed to sit comfortably beneath daily wear. The artisan finish reveals fine details in the prongs and shank, ensuring durability without sacrificing elegance. The cool white gold complements the marquise’s glassy brilliance, while the semi-set design invites you to select a lab-grown diamond that meets your clarity and cut preferences.

Crafted with lab-grown diamonds, this ring supports a more sustainable approach to fine jewelry, reducing environmental impact without compromising on radiance or quality.

Its slender band and modest height make this ring ideal for those who appreciate a sleek, glove-friendly fit or enjoy stacking with complementary bands. The marquise shape’s tapered points elongate the finger, lending a graceful, architectural presence that suits both classic and modern tastes.
