Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a hand, where a marquise diamond’s tapered points catch light with a quiet, refined drama. This semi-set halo engagement ring in 14K white gold frames a 12 x 6 mm marquise center, designed to amplify brilliance while maintaining a low profile for everyday grace.

Crafted in Williamsburg, the band is smoothly finished with a comfort fit, ensuring it rests naturally without catching. The halo setting enhances the stone’s silhouette, adding dimension without bulk, making it ideal for stacking or solo wear. Each piece undergoes meticulous hand inspection to meet exacting standards of polish and symmetry.

Our diamonds are lab-grown, offering clarity and sparkle with a smaller environmental footprint, reflecting a commitment to ethical jewelry without compromise.

The elongated marquise shape flatters slender fingers and pairs well with delicate bands, while the low-profile setting slips easily under gloves or sleeves, perfect for daily life in Brooklyn’s varied rhythms.

Should you need resizing, our studio provides precise adjustments to maintain comfort and balance. Typical lead times accommodate thoughtful customization without rush.
