Deep purple amethysts, olive green peridots and a luminescent pearl are a stunningly beautiful combination in the nature-inspired design of the 14K. Solid Gold Necklace with Amethyst, Peridots and Pearl. The necklace's pendant is made up of a wavy solid gold bar that branches out to gemstone settings. A pearl set at the lower center of the pendant is the star of the show. A round-cut peridot is positioned on each side of the pearl, and teardrop-cut amethysts are set above them. With its wavy solid gold bar and gemstone settings, the pendant resemble a tree branch decorated with leaves and buds.
