The word Agate comes from the Greek name for a stone originally found in the Achates River in Sicily (currently known as Drillo River). Agate has been found with the remains of Stone Age man in France from as early as 20,000-16,000 B.C. and the Egyptians used agates prior to 3000 B.C. for talismans, amulets, seals, rings and vessels. Early civilizations used eye beads to protect them from evil and bring good luck. They created eye beads by carving a hole through an agate disc.

Although agate is found all over the world, the most exceptional specimens come from Southern Brazil and Northern Uruguay. However, the moss agates of Colorado and Montana are equal in beauty and some beautiful specimens have been found in Mexico and California, U.S. A geode type of agate, called “Thunder Egg” by Native American Indians, is found in Oregon. Fire agates come from Mexico and Arizona. Commercial deposits exist in China, Mexico, India, Madagascar, and the U.S. along the shores of Lake Superior agates are found all over the world where highly pressurized hot water rich in silica filled crevices and vugs.

The outer surface of an agate is rough, pitted and ugly. It masks the beauty of the crystal inside. However, the crust is weak and somewhat fragile and over centuries it is washed away allowing the gemstone to be discovered along rivers and streams.

Agate is a microcrystalline variety of chalcedony, which occur in nodular masses in volcanic lava rocks. They form in concentric layers and fill cavities in a host rock. The results are round nodules bands similar to tree trunks and may appear as eyes, scallops, or as landscapes with dendrites that look like trees. This last type is called Tree Agate or Moss Agate. Many fossils are actually agatized material that replaced an organic substance such as wood. Many varieties of petrified wood are used for jewelry an ornamental purposes because the original structure has been replaced with agate.

Agate occurs in most colors including black, gray, brown, reddish, green, pink, blue, and yellow from transparent to opaque. Today, many of these stones are artificially dyed to enhance the depth of color and to produce more vivid tones than those found in nature.
