Lab-Grown Diamond Engagement Ring

Imagine the subtle sparkle of a 15 mm round diamond poised to catch light with every movement, framed by a delicate halo that amplifies its brilliance without overwhelming. This semi-set engagement ring foundation in 18K palladium white offers a refined, low-profile silhouette designed for everyday grace.

Crafted in Williamsburg, Brooklyn, the band’s cool palladium finish ensures durability and a comfortable fit that slides easily beneath gloves or alongside stackable bands. The halo setting is engineered to enhance the center stone’s classic round cut—known for its balanced fire and scintillation—while maintaining a sleek, unobtrusive profile.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that combine clarity with sustainability. The semi-set design invites you to select a center stone that resonates personally, allowing for a truly custom expression.

Ideal for those who value both modern craftsmanship and subtle elegance, this mounting suits a range of hand sizes and lifestyles, offering a secure yet refined foundation for your engagement ring. Resizing is available to ensure a perfect fit without compromising the band’s integrity.
