Editing Agate (section)

=== South America ===
* ''Brazilian agate'' is probably one of the largest agates. They can reach {{convert|0.9|m|ft|abbr=on}} in diameter and weigh over {{convert|120|kg|lb|abbr=on}}. Brazilian agate is found primarily as nodules and geodes in decomposed volcanic ash and basalt of [[Lopingian|Late Permian]] age. The largest deposits are in the Brazilian state of [[Rio Grande do Sul]], but significant amounts can also be found throughout southeastern [[Brazil]]. Some specimens can be very colorful and include features such as eyes, tubes, dendrites, and sagentite. However, most Brazilian agate that is mined is naturally pale yellow, gray, or colorless and artificially dyed before being brought to market.
* [[Condor agate|''Condor agates'']] are found in the [[Mendoza Province|Mendoza]] province of [[Argentina]]. They typically have bright red and yellow fortification banding and may contain mossy or sagenitic inclusions. Other varieties of agate can also be found in the [[Patagonia]] area of Argentina, including ''crater agate'' (typically hollow nodules with black and red bands) and ''puma agate'' (agatized coral). 
* [[Uruguay]] was the first major source of agates in South America. Agates were discovered there in 1830, but sources in neighboring Brazil became more popular in the late 19th and 20th centuries.
* Agates have also been found in [[Chile]] and [[Peru]].<ref name="pabian" />{{rp|pp=122–131}}
