Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set halo ring invites you to choose a center stone that measures 10 by 5 millimeters, offering a striking balance between presence and elegance.

Crafted from warm 10K yellow gold, the band is shaped and polished in our Williamsburg studio, where each curve is refined for a smooth, comfortable fit. The halo setting, designed to cradle your chosen marquise, enhances the stone’s natural brilliance while maintaining a low profile that slips easily beneath gloves or daily wear.

Our commitment to sustainability is reflected in the lab-grown diamond option, ensuring clarity and sparkle without compromise to the earth.

This ring suits those who appreciate architectural drama paired with artisan detail—its slender band and halo frame elongate the finger while remaining subtle enough for stacking alongside wedding bands or personal treasures.

Should you need resizing, our in-house jewelers handle adjustments with care, ensuring your ring fits perfectly.
