Banded Agate (Kerrouchen) For Sale

Banded agate nodules from Kerrouchen (also spelled Karouchen or Kerrouchene) are known for their intense red, pink, white, yellow, orange and brown agate hues. They formed as nodules from silica and iron-rich fluids within the Triassic-aged basaltic rock. These nodules can reach upwards of 12 inches wide and can be collected from the basalt itself, or more commonly from the apple farms in the valleys where farming exposes these nodules that eroded out of the basalt. Both nodular and vein/seam agates come from this region of the Atlas Mountains.

What Is Agate?

Agate is a variety of microcrystalline quartz (chalcedony) that displays translucence and, in some cases, banding. Agate primarily forms when silica-rich fluids fill pockets within rock and/or fossils, depositing silica on exposed surfaces. This process can result in banding patterns as the composition and impurities of the fluids change over time. These banding patterns can either form as flat layers called waterlines or or rounded layers, depending on the surfaces available for deposition.
