Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This 12 x 6 mm center stone is embraced by a halo of meticulously set pavé diamonds, amplifying its glassy, tapered elegance within a cool platinum frame.

Handcrafted in our Williamsburg studio, the ring features a low-profile halo setting designed for everyday wear, balancing brilliance with comfort. The platinum band is polished to a satin finish that feels smooth against the skin, while the secure prong setting protects the delicate points of the marquise shape without adding bulk.

Each diamond is lab-grown, offering a clarity and sparkle that honors both ethical sourcing and environmental mindfulness. This ring’s refined silhouette suits those who appreciate architectural grace paired with artisan craftsmanship.

Its slender band and modest height make it ideal for stacking alongside wedding bands or wearing solo with ease—glove-friendly and designed to move naturally with your hand. Resizing is available to ensure a precise fit, crafted carefully to maintain the integrity of the halo setting.
