Lab-Grown Diamond Engagement Ring

When sunlight catches the slender points of a marquise diamond, it traces a delicate arc of light that seems to elongate the hand with quiet elegance. This semi-set solitaire ring invites you to choose a 6 x 3.5 mm marquise center stone, its signature shape offering a graceful, tapered silhouette that balances vintage charm with modern refinement.

Crafted from 18K white gold, the mounting features a low-profile setting designed for everyday wear, its smooth band gently rounded for comfort and ease beneath gloves or alongside other rings. Each piece is meticulously finished in our Williamsburg studio, where precision meets a subtle polish that enhances the diamond’s natural brilliance without distraction.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, offering clarity and sparkle with a lighter environmental footprint. This ring suits those who appreciate a refined statement—whether worn solo or stacked with complementary bands, its slender form complements slender to medium finger shapes gracefully.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as natural as it looks. Lead times for custom center stones vary, and we’re happy to guide you through the selection process.
