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, 6.5-7 on the Mohs scale, 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. The stone in this pendant is not dyed and shows the dramatic coloring found in Montana agates.



There are thousands of localities worldwide where agate specimens have been found, many of these are named for the locality. Some areas with exceptionally beautiful specimens have been depleted by over mining, but because agate is so common there are usually several new discoveries each year.

History and Interesting Facts:

The hobby of collecting bowls made of agate was popular during the renaissance and this activity was responsible for the growth of the lapidary industry near Idar-Oberstein in Germany. Although agate beds were originally found in that area, most of the local deposits were depleted in the nineteenth century and the majority of agate coming out of the shops in Idar-Oberstein today are imported from Brazil.

Many Gem and Mineral shows sponsor old time rock hounds that bring hundreds of geodes to break open with a specially made tool that "pops" the geode open leaving the internal material undamaged. Crowds that gather at his booth pay a few dollars in hopes of owning a beautiful specimen full of amethyst or citrine crystals. Agate geodes can be very small (as small as a fruit seed) or very large. The largest geode ever mined was found in Brazil and weighed almost two tons.

Agate is the state gemstone (or stone, rock) of: Kentucky (Rock) - Kentucky Agate; Louisiana and Montana (gemstone) - Agate; Tennessee (stone) - Agate; Minnesota (gemstone)- Lake Superior Agate; Nebraska (gem) - Blue Agate; South Dakota (gemstone) - Fairburn Agate ; Nebraska (rock) - Prairie Agate; Arizona (mineral - unofficial) - Fire Agate.

Besides its use in jewelry, vessels, and ornamental objects, children's marbles were once made of agate and were called "aggies" in reference to their composition.
