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 market for Brazilian agates is for 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).

Our preference is to locate the agates whole and cut
and polish them in our shop. We generally do 1/2
nodules or 1/3 cuts with polished faces. We like to find
those 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. The 3.4 lb perfect agate listed first
has the most brilliant shine...like glass.

| These Brazilian Agate slabs are Old Stock Agate, procured through reputable sources and some are even from the Comstock Pewter Factory in Durango Colorado. They purchased these through the mid to late 90's, then went out of business a few years later. We have not seen this nicer quality agate from Brazil for quite a few years. We believe that Brazil is "high grading" their current stock that they sell, so the collecting world does not have the chance to get the best quality agate at wholesale pricing. Most of the Brazilian agate imported lately is lower quality agate that is dyed to make it look better or smaller specimens pre-cut and polished as "export" agate. Brazilian agate rough stock has become harder to find in the past few years, and the quality has decreased significantly. |
