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
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.

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.
Skip-an-atom agates form when the initial agate formation process is disrupted or halted, leading to irregular banding patterns and gaps in the crystal structure. This can be caused by changes in the mineral composition, temperature, or pressure during formation. The skipping of atoms results in unique and visually striking patterns in the agate.
Agates are none of the above rock types, but a form of the mineral quartz, normally formed as a gas vesicle filler in igneous rocks, the microcrystalline quartz gradually filling the cavity with successive layers.
