There are at least 15 major agate-producing areas in 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.

Unique White Skin Agate Hollow
Display Nodule

$75.00
This Brazilian agate was cut and polished in our shop in Las Vegas in 2004. The other half was sold shortly thereafter. We kept this
in our collection for many years due to how unique this type of Agate is. When we cut it open the center was full of mud and mineral
granules that had not yet solidified. As Agates go, this is a very young one. This one has a large open vug center framed in a thick
clear to brown Chalcedony  layer with a white skin rind. 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. New acrylic 3 post clear display stand included
