The Duet is a lab grown diamond open ring that reimagines the toi et moi in miniature — an emerald-cut diamond paired with a marquise on opposite ends of an open band, each stone distinct in shape but perfectly balanced together. The open design sits flush against virtually any engagement ring style, making it one of the most stackable diamond rings for women who want a bridal set that feels curated rather than matched. Available in yellow, white, or rose gold in 14K. Wears equally well solo as an everyday diamond fashion ring. Handcrafted in NYC.
