Approximately 1 1/2" long and 1" wide/
Oxidized, Polished and Sealed Copper
This Slaughter Mountain AZ fire agate was purchased rough and tumbled by myself. Fire Agate is difficult to tumble, as you need to make sure you do not polish off the "fire" in the store.
Fire agate, a variety of chalcedony, is a semi-precious natural gemstone discovered so far only in certain areas of central and northern Mexico and the southwestern United States (New Mexico, Arizona and California). Approximately 24-36 million years ago these areas were subjected to massive volcanic activity during the Tertiary Period. The fire agates were formed during this period of volcanism when hot water, saturated with silica and iron oxide, repeatedly filled cracks and bubbles in the surrounding rock.
Fire agates have beautiful iridescent rainbow colors, similar to opal.
