Lab-Grown Diamond Engagement Ring

When light catches the elongated facets of a marquise diamond, it creates a striking silhouette that both sharpens and softens the hand’s natural lines. This semi-set halo ring foundation in 10K white gold is crafted with a delicate balance of strength and finesse, designed to cradle a 6 x 3.5 mm marquise center stone with precision.

Each band is hand-finished in our Williamsburg studio, where the low-profile halo setting is carefully shaped to enhance brilliance without adding bulk—ideal for daily wear and layering. The smooth comfort fit ensures the ring sits gently, while the halo’s artisan prongs reflect meticulous attention to detail, securing your stone with subtle elegance.

Our commitment to lab-grown diamonds means this piece carries a clarity and sparkle born from sustainable practices, reducing environmental impact without compromising beauty.

Its slender silhouette suits those who appreciate refined geometry and a ring that complements rather than competes with their lifestyle—perfect for stacking or wearing solo with ease. The semi-set design invites you to select a marquise diamond that speaks to your personal story.

Should you need resizing or custom adjustments, our Brooklyn studio offers thoughtful consultations to ensure a flawless fit and finish.
