Lab-Grown Diamond Engagement Ring

Sunlight catches the marquise diamond’s elongated silhouette, casting a delicate sparkle that gently follows the curve of your finger. This semi-set halo engagement ring in 10K rose gold frames an 8 x 4 mm marquise stone, known for its graceful taper and subtle drama.

Crafted with a low-profile halo setting, the ring balances brilliance with everyday comfort, designed to sit close to the hand without catching. The warm blush of rose gold complements the diamond’s crisp facets, while the secure prong setting ensures durability for daily wear. Each piece is meticulously finished and inspected in our Williamsburg studio, reflecting a commitment to precision and refined craftsmanship.

Our lab-grown diamonds offer a clear, sustainable alternative, reducing environmental impact without compromising on clarity or fire. The slender band and modest height make this ring ideal for those seeking a refined silhouette that layers effortlessly with other bands or stands elegantly alone.

Should you need a custom fit, resizing is available to ensure the ring feels as natural as it looks. Typical lead times accommodate careful handcrafting and quality assurance.
