This cocktail halo ring is dripping with vibrancy and scintillation. An 5.87 carat square cushion cut, natural vivid yellow sapphire is obviously notable. The gem source is Sri Lanka; its transparency and luster are excellent. Its color is evenly distributed throughout the gem. It has mixed cut diamonds on the band that total up to .61carats. All in brightly polished 18k white gold. The saturation of this gem is remarkable.
