Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a graceful, tapered brilliance. This semi-set three-stone engagement ring in 14K white gold offers a refined foundation, handcrafted in our Williamsburg studio to cradle a 9 by 4.5 mm center stone with precision and care.

The band’s smooth finish and balanced weight ensure a comfortable fit for daily wear, while the three-stone setting adds depth without excess height—ideal for those seeking a low-profile yet striking design. Each prong is meticulously shaped to secure the marquise’s pointed ends, a detail that speaks to our artisan approach and rigorous inspection process.

Crafted exclusively with lab-grown diamonds, this ring reflects a commitment to ethical jewelry that reduces environmental impact without compromising on clarity or fire. The cool sheen of 14K white gold complements the marquise’s glassy facets, enhancing its architectural elegance.

Designed for someone who appreciates modern geometry and subtle statement, this mounting suits slender to medium finger sizes and pairs effortlessly with stacking bands or a wedding ring. Its low profile makes it glove-friendly and practical for everyday life.

Should you wish to adjust sizing or explore stone options, our Brooklyn studio offers personalized consultations to ensure your ring fits perfectly and reflects your vision.
