Lab-Grown Diamond Engagement Ring

Imagine the quiet gleam of a 12 mm round diamond poised to catch light with every subtle movement. This semi-set halo ring foundation in 18K palladium white offers a low-profile silhouette designed for daily wear, balancing presence with comfort.

Crafted in Williamsburg, the band’s palladium alloy provides a durable yet lightweight frame, finished to a smooth comfort fit that slides easily beneath gloves or alongside other stackable pieces. The halo setting’s delicate rim will amplify the center stone’s brilliance once set, while maintaining a refined, unobtrusive profile.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that deliver clarity and sparkle without compromise. The cool white metal complements the round shape’s classic fire and scintillation, ideal for those seeking a blend of tradition and modern practicality.

Designed for hands that appreciate subtle strength, this mounting suits a variety of finger sizes and shapes, with resizing available to ensure a precise fit. Its low height and smooth edges make it an excellent choice for everyday life, from Brooklyn’s studios to city streets.
