Agates
Brazil, Lake Superior region, Montana, Mexico and Germany.
As you can see Brazil is where a lot of the crystals come from. The bigest rock crystal was found in Brazil.
Most good crystals are obtained in the mineral veins where quartz is found.Big quartz crystals are often found near hot springsThey can also be obtained from geodes, granite porphyries, and granite pegmatities.
