Agatul e o varietate microcristalina de silice, in deosebi calcedonie, si se gaseste in rocile vulcanice, dar si in cele metamorfice. Agatul se formeaza in cavitatile rocilor vulcanice rezultate dupa volatilizarea elementelor lavei, care sunt umplute cu material silicios dispus sub forma de lamine, de unde si aspectul observabil caracteristic. Lustruit, agatul are valoare decorativa.

Agate is a silica variety, mostly of chalcedony, found in volcanic rocks and sometimes in metamorphic ones also. Agate is formed in the cavities of volcanic rocks by thin layering of the silica, hence the typical structure. If polished, agate has decorative value. Otherwise it is used in industry.
