Deep azure captured in geometric perfection — a 2.5 carat fancy blue asscher-cut lab grown diamond set in a hidden halo with 25 round brilliant accent diamonds. The asscher cut’s step-cut faceting creates cascading layers of blue light, like looking into the deepest part of the ocean. Blue diamonds are the rarest of all fancy colors, and the asscher’s unique light pattern makes the blue appear even deeper and more saturated than in brilliant-cut shapes. The hidden halo beneath the center stone adds a ring of white sparkle that frames the blue beautifully from every side angle. This is a sapphire’s intensity with a diamond’s unmatched fire.
