A vivid green that commands attention — a 3 carat vivid green princess cut lab grown diamond set in a hidden halo with 24 round brilliant accent diamonds. The princess cut’s sharp, angular facets give the green diamond a lively, architectural sparkle — while round cuts scatter green light softly, the princess cut focuses it into bold, geometric flashes like sunlight striking through a crystal forest. The hidden halo adds a secret ring of sparkle beneath the center stone, making it appear larger without disrupting the clean, modern princess silhouette. Unlike emeralds (7.5–8 Mohs, prone to chipping and clouding), green diamonds rate a 10 on the Mohs hardness scale — this ring will look as vivid in 50 years as it does today.
