Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated points of this marquise shape, it casts a subtle, elegant shadow that draws the eye along the finger’s natural line. This solitaire semi-set in 10K yellow gold offers a refined foundation for an 8 x 4 mm lab-grown diamond, designed with a low-profile setting that sits close to the hand for everyday comfort.

Crafted in Williamsburg, the band is smoothly finished with a comfort fit that eases wear throughout daily life, while the secure prong setting balances protection with light exposure to maximize brilliance. The semi-set design invites you to select a center stone that reflects your personal story, ensuring a truly custom engagement experience.

Each diamond is ethically sourced through lab-grown technology, reducing environmental impact without compromising on clarity or sparkle. The warm yellow gold complements the marquise’s tapered drama, making it a graceful choice for those who appreciate subtle sophistication and a sleek silhouette.

Its slender profile works well alone or stacked with complementary bands, and the secure setting accommodates a variety of hand shapes and sizes. Resizing is available to ensure the perfect fit, crafted with the same attention to detail as every piece from our Brooklyn studio.
