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).
| Excellent large natural Brazilian agate end cut with bottom cut flat for display. This excellent specimen has a colorful display with excellent fortification lines and exceptional growth patterns. There is an area of white to clear quartz with almost a vug formation. It is EXTREMELY HARD to find specimens this size without massive natural cracks or other imperfections. We were extremely lucky finding these specimens! This piece measures approximately 8 x 8 x 1-1/2 " and weighs 7.6 lbs! The face is highly polished! EXCELLENT DISPLAY!!! |
| Rarely does one find a Brazilian agate without natural fractures or cracks. This one is XL and as perfect as nature allows. There are no visible fractures on this one! This agate has a blindingly high gloss polished finish as well. This XL Agate slab is from Brazil. It comes with a large plastic stand. The first pictures show the Agate viewed next to a window. Other pics are how it would look not backed by light. Polished on both sides. The slab measures 13" by 9 3/8" by 3/8" thick. It weighs 3 pounds 6 oz. Excellent condition! Beautiful display Agate. |

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.
