This stunning necklace captures the natural beauty of Chalcedony, a microcrystalline. Its unique milky green-blue color is enhanced by the facets that allow it to reflect flashes of light. Adding a hint of femininity to this large stone are just under a half carat of diamonds (0.45 total carat weight). The Chain is 18k, 18 inches and is interspersed with Green Amethyst.
