Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it reveals a subtle drama that stretches gracefully across the finger. This semi-set halo engagement ring in 10K white gold frames a 12 x 6 mm marquise center with a delicate halo that enhances its brilliance without adding bulk.

Crafted with a low-profile setting, the band sits close to the finger, ensuring comfort and ease for daily wear. The smooth finish and precise prong work reflect careful inspection and hand-finishing in our Williamsburg studio, designed to withstand everyday moments without sacrificing elegance.

Our commitment to lab-grown diamonds means this ring carries a clarity and sparkle born from sustainable practices, offering a conscious choice without compromise.

The elongated marquise shape visually lengthens the hand, ideal for those who appreciate a refined yet distinctive silhouette. Its halo setting adds subtle sparkle while maintaining a sleek profile, making it compatible with stacking or a solitaire for versatile styling.

Should you need resizing, our in-house artisans handle adjustments with care to preserve the ring’s integrity and comfort fit.
