Brazilian Agate Slabs

Many of the Brazilian Agate slabs listed here are Agate specimens we procured from two Old Stock sources. Some are from the Old Comstock Pewter Factory in Durango Colorado which operated in the 1990.s.

Some of the agate slabs listed here came from the E&L Roth Collection which is over 34 years old. Some of these amazing old stock slabs have stunning dendrites (moss) and are the larger size agates which have not been available for many years now.

Brazil has been "top grading" their agates, which have pretty much all been sold off to China. The Brazilian agate imported to the USA 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 with the quality decreasing significantly. It's nice to find some desirable old stock specimens from time to time. It is typical and normal to see that the majority of agate slabs will have natural fractures due to the brittleness of the agates.
