Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, graceful shadow across the hand. This semi-set halo ring invites your choice of an 8 x 4 mm lab-grown marquise center, framed by a delicate halo that amplifies its sculptural silhouette.

Crafted from warm 18K rose gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit, designed for everyday wear without catching or pinching. The halo setting is meticulously hand-set, enhancing the diamond’s brilliance while maintaining a low profile that slips easily beneath gloves or sleeves.

Each lab-grown diamond reflects a commitment to sustainable luxury, offering clarity and sparkle with a lighter environmental footprint. The rose gold’s gentle blush complements the marquise’s vintage-inspired drama, making this ring a refined choice for those who appreciate artisan craftsmanship and ethical sourcing.

Its slender band and low-profile halo suit slender to medium finger sizes, balancing bold geometry with subtle elegance. Whether worn alone or stacked with complementary bands, this ring adapts seamlessly to daily life and personal style.

Should you wish to adjust the band size or explore custom details, our Brooklyn studio offers personalized consultations with thoughtful timelines and care guidance.
