Fire Agate is the result of Agate forming between thin layers of iron oxide crystals. The crystals then become the white matrix seen in the stone. It is a natural, untreated stone that is found in Mexico and Brazil. This ring features an 18x25mm rectangle of Fire Agate. A simple elegant Sterling Silver bezel surrounds the stone and the open band is decorated with wire swirls and beads. This ring was designed by Marianna and Richard and handcrafted by Balinese Artisans. It measures 1 1/4" top to bottom and has been left open in the back for adjusting up to one size larger.
