The listing, *** Big, Beautiful,Natural Agate!!!! *** has ended.
The agates from Brazil are mostly mined from decomposed volcanic ash and basalt from the late Permian age (248-275 million years ago) In Rio Grande do Sul the "agate mines" are normally just plowed fields in which loose agates are found and collected. Brazilian agates are very colorful stones with some of the most beautiful inclusion and structures imaginable. Agate is very hard and takes an excellent polish..
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 Utah ,Mexico and California. A geode type of agate, called "Thunder Egg" by Native American Indians, is found in Oregon and Utah. Fire agates come from Mexico and Arizona. Deposits exist in China, Mexico, India, Madagascar, and the USA along the shores of Lake Superior. Agates are found all over the world wherever highly pressurized hot water rich in silica filled crevices and vugs. Often tiny quartz crystals form within the stone and add to the beauty and uniqueness of individual stones. These crystals are called drusy (sometimes misspelled as druzy).
