A 1.70-carat round peridot with 0.55 carats of white topaz accents in rhodium over sterling silver creates a colored gemstone ring where the vivid lime-green of peridot is framed by the sparkle of genuine topaz. Peridot's color is specific and recognizable: the warm, slightly olive-tinted lime green of fine olivine - a color that no other gemstone quite replicates and that appears particularly beautiful in daylight and under natural light. The white topaz accents provide the white sparkle contrast that makes the green appear more saturated. Note: no proprietary color name used - this is simply peridot with its own natural character.
