Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc of brilliance that feels both intimate and bold. This semi-set halo engagement ring in polished platinum frames a 15 by 7.5 mm marquise center, inviting you to choose a stone that will become the heart of your story.

Crafted with precision in our Williamsburg studio, the setting’s halo of micro-pavé diamonds enhances the marquise’s tapered drama while maintaining a low-profile silhouette that rests comfortably against the finger. The platinum band’s smooth finish and subtle weight offer a reassuring presence for daily wear, designed to complement the hand’s natural lines without overwhelming.

Each lab-grown diamond selected for this design reflects a commitment to ethical sourcing and environmental mindfulness, embodying a modern approach to luxury without compromise.

Ideal for those who appreciate a blend of vintage-inspired romance and contemporary refinement, this ring suits slender to medium finger shapes, elongating the hand with its graceful form. Its low profile and secure setting make it glove-friendly and stackable with complementary bands.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as personal as the moment it celebrates.
