Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances along the warm blush of 18K rose gold. This semi-set engagement ring invites your choice of a 10 x 5 mm marquise center, its tapered points echoing the subtle drama of vintage elegance with a modern edge.

Handcrafted in our Williamsburg studio, the band’s artisan finish reveals meticulous attention: softly rounded edges for comfort, a low-profile setting that slips easily beneath gloves or alongside stackable bands, and delicate accent stones that frame the center without overpowering its refined shape. Each ring undergoes rigorous inspection to ensure the smoothness of the rose gold’s satin polish and the security of every prong.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint.

Designed for those who appreciate subtle statement pieces, this ring complements slender fingers and balances well with other fine bands. Its low profile and comfort fit make it a daily companion, whether worn solo or stacked.
