In all probability, yes. Uranium and its various daughter radionuclides are a natural part of the Earth, so everything of Earth origin, theoretically, has some uranium in it. Its just a matter of being able to detect it, because the levels in an individual sample will be very, very low, usually too low to detect.
While an individual agate may display special colors and patterns that can make them highly desireable to rockhounds or other collectors it is not considered a "precious" stone. It is possible to find numerous examples that have sold for more than a hundred dollars. any gemstone of extremely very good quality will be called precious. So all agates are not precious only few agates of very very good quality can be called precious same way all diamonds are not precious, only very good quality diamonds can be a called precious.
They aren't found in igneous matrix only. Agates are formed in gas cavities in volcanic rock, as well as in cracks and holes in metamorphic and sedimentary rocks. Solutions high in silica content filled these cavities to form silica gel which hardened to the agate we know. Generally, the formation temperatures are now thought to have been between 40 and 270degrees centigrade, perhaps more to the lower end of this range. Theory of agate formation has evolved with better microscopes and continued study over the years. Books by Roger K. Pabian are recommended. At any rate, there were no human witnesses to the formation of agates, and we are still learning about these fascinating gems.
Some of the gemstones found in Washington State include agates, jaspers, petrified wood, and garnets. Additionally, there are also reported findings of opals, quartz crystals, and fossils in certain areas of the state.
Opals are not commonly found in Washington state. They are primarily found in countries like Australia, Mexico, and Brazil. Washington is more known for its variety of other gemstones like agates, garnets, and petrified wood.
yes oxyx is a semi-precious stone. It is an agate. Most of the onyx in the market today are heat treated agates
semi precious

As with most things, agate hunting is an acquired skill and simply reading the answer will not make you an expert! The following field guide will give you some tips on how and where to find agates on a pebble beach. Bret Fogelberg http://www.123agates.com/subpages/fieldguide.pdf
No, opals are not agates. Opals are a type of mineraloid composed of hydrated silica and are known for their unique play of color, while agates are a variety of chalcedony, also composed of silica but with a more crystalline structure. Both are silica-based, but their formation processes and appearances differ significantly.
Agates can be found in various places around the world, including river beds, volcanic rocks, and areas with geothermal activity. Some popular locations for finding agates include the beaches of Lake Superior in the United States, the coasts of Brazil and Uruguay, and the state of Gujarat in India. Additionally, agates can also be found in certain regions of Australia, Mexico, and Germany, among others.
Moss Agate and Turritella Agate

Agates form in igneous rocks such as lava flows and in sedimentary rocks such as limestone and shale. They are typically found in volcanic and metamorphic environments, where silica-rich fluids are able to penetrate cavities in the rock, forming the characteristic banded patterns that agates are known for.
The value of agates can vary greatly depending on factors like size, quality, and color. In general, the price of agates can range from a few dollars per pound for common varieties to hundreds of dollars per pound for rarer and more valuable specimens.
Agates have been found and used for ornamental purposes for thousands of years. They are typically formed in igneous rock formations and have been collected by humans for their beauty and believed metaphysical properties.
Tennessee Agates are primarily found in the areas surrounding the Cumberland Plateau in Tennessee, United States. Some specific locations include the counties of Smith, Warren, and White.
