Brazilian Agates
There are at least 15 major Brazilian Agate-producing areas in the country of Brazil. 12 of these are located in the 5 most southeastern states of the country, Rio Grande do Sul, immediately north of Uruguay, being the best known. Other areas include Santa Catarina, Paraná, Sao Paolo, and Minas Gerais. Two other areas are in the state of Bahia in east central Brazil and another located in the state of Roraima in the extreme northwest. Polyhedroid Agates come exclusively from Paraiba.
Agates were discovered in the late 1920's by a geologist named B.V. Freyburg with the Geological Survey of Argentina. Current laws in Brazil prohibit the export of unfinished agate
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.
Sadly, most of the Brazilian Agates you find for sale today are the "dyed" versions of these stones. When you see a pink, teal, purple or green agate it is dyed not natural. We have a few dyed bookend sets, but prefer to deal only in natural agates. We purchase some cut agates from Brazil, ones with the bottoms cut flat for display or cathedrals (man made cement type coatings).
We take great pleasure in finding the agates whole then cutting and polishing them in our shop. We generally produce 1/3 to 1/2 nodules with polished faces. We like to find those surprise "inner treasures".
We sell most agates this way, but do from time to time cut some slabs for sale. You can make many slabs out of one nodule. Our slabs for sale will normally be cut and not polished.

This Brazilian agate was cut and polished in our shop in Las Vegas in 2004. The other half was sold shortly thereafter.

This Agate is very interesting...Chris calls this her cave. The bottom of the vug is flat with a drain chase and the top of the vug is a shallow botryoidal formation with a 0.35" (9mm) diameter hole in the top...Chris's vent for the heating fires in her cave rock.
