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 a 13x18mm rectangle of Fire Agate. A simple elegant row of Sterling Silver beads decorate each side. This ring was designed by Marianna and Richard and handcrafted by Balinese Artisans.
