Introducing the Guy Harvey Flying Fish necklace in Sterling Silver. We use the same age old enameling process as Faberge and Tiffany to bring color to Guy Harvey Jewelry. The enameling process used for the wings is known as Plique-a-jour which is French for "letting in daylight". It is a vitreous enameling technique where the enamel is applied in openings like stained glass. The fishes eye is accented with a Black Diamond. Each piece comes with a numbered certificate of authenticity, gift pouch and Guy Harvey gift box.
