Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow that feels both bold and intimate. This semi-set engagement ring foundation in 18K white gold is crafted in our Williamsburg studio, where each curve of the low-profile band is hand-finished for a smooth, comfortable fit that sits close to the finger.

The marquise shape, measuring 12 by 6 millimeters, offers a dramatic yet elegant presence, its pointed ends drawing the eye along the length of the hand. The solitaire setting is designed to showcase your chosen center stone with minimal metal interference, allowing the diamond’s facets to sparkle freely while maintaining everyday wearability.

Our commitment to sustainability is reflected in the exclusive use of lab-grown diamonds, offering clarity and ethical provenance without compromise. The 18K white gold band is polished to a subtle sheen, balancing durability with refined craftsmanship.

Ideal for those who appreciate architectural lines and a ring that layers effortlessly with wedding bands or stackable rings, this mounting suits slender to medium finger sizes and fits comfortably beneath gloves or sleeves. Resizing is available to ensure a precise fit, tailored to your lifestyle.
