This is the Emerald City Ring made with jade, moonstone, and emerald on a light green background and glows white. While rings with opal are more reflective, this ring has more of a matte finish. It is made with materials that have calming tones of green. The moonstone and the emerald are translucent, giving the ring depth and dimension. The ring band is made of Tungsten-Carbide, which is very durable, scratch-resistant, and has a nice heft to it. This ring is perfect for all occasions and can even make the perfect wedding band. The ring comes 6mm wide (standard women's width) or 8mm wide (standard men's width).
