Lab-Grown Diamond Engagement Ring

When light catches the elongated points of a marquise diamond, it creates a striking silhouette that both sharpens and softens the hand’s natural lines. This semi-set halo engagement ring in 18K white gold frames a 12 x 6 mm marquise center with a delicate circle of pavé stones, enhancing brilliance without adding bulk.

Crafted for everyday wear, the low-profile setting keeps the diamond close to the finger, reducing snag risk while maintaining a refined presence. The polished white gold band is shaped for comfort, its subtle taper balancing the stone’s dramatic length. Each piece is finished and inspected in our Williamsburg studio to ensure precise fit and lasting durability.

Our commitment to ethical jewelry is reflected in the lab-grown diamond’s clarity and sustainability, offering a conscious alternative without compromise on sparkle or structure.

This design suits those who appreciate architectural elegance paired with practical wearability—ideal for slender to medium finger sizes and compatible with stacking or a wedding band. The semi-set mounting invites you to select your own marquise stone, allowing for a personalized centerpiece.

Resizing is available to ensure the ring fits seamlessly, and care instructions accompany every purchase to maintain its luminous finish.
