This is a one-of-a-kind custom ring for KAORU-san. The gemstone is Ametrine, a combination of amethyst and citrine. It's a rare stone, with the purple of amethyst and the color of citrine blending together. It's hard to tell from the image, but the color changes depending on the angle. This was custom-made with the stone of my choice. It's rare.
