Fire Agate is a deep brick red or orange stone that 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. In these earrings we find 8x12mm Fire Agate stones between Sterling Silver caps. These earrings were designed by Marianna and Richard and handmade by Balinese Artisans they measure 1 3/4" long from the ear.
