Purple and green semiprecious gemstones contrast beautifully in the stunning 14K. white gold Necklace with Diamond, Purple Amethyst & Peridot. A diamond accent at the center of the pendant is surrounded by the pretty purple of amethyst and the olive green of peridot. The marquis-cut amethyst and peridots surround the diamond and alternate to form a floral pattern. An additional amethyst at the bottom of the flower gives the pendant a long vertical line and makes the pendant stand at 1.3 inches. This amethyst stem catches the eye and draws it up and down the length of the pretty pendant.
