Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, dramatic silhouette that feels both bold and intimate on the hand. This three-stone engagement ring is crafted from cool 14K white gold, its polished band a subtle stage for the 12 x 6 mm marquise center flanked by two delicately tapered side stones.

Each gem is securely nestled in a low-profile setting, designed for everyday wear without catching or discomfort. The band’s smooth finish and balanced weight offer a comfort fit that slides easily beneath gloves or alongside other stackable rings.

Our studio’s artisan approach ensures every facet is inspected and every prong hand-finished in Williamsburg, Brooklyn, where modern precision meets thoughtful craft. The lab-grown diamonds deliver a clarity and fire that rival mined stones, with a fraction of the environmental impact.

Ideal for those drawn to architectural elegance and a ring that complements a confident, modern lifestyle. The three-stone layout adds symbolic depth, perfect for marking a shared journey.
