Brazilian Agate BookendsBrazilian Agate Bookends

   
Rocks, Minerals, and FossilsThese Brazilian Agate Bookends are cut from Brazilian Agate Geodes.  The faces have been polished to a smooth glassy finish, with the outside left rough.  Small cork circles on the bases protect your furniture.

Geodes are spheroidal masses that form inside hollow cavities in volcanic or sedimentary rocks, most commonly basaltic lavas and limestones.  The cavities themselves may have been gas bubbles in magma, or may have formed when nodules inside sedimentary rocks dissolved.

As mineral-laden groundwater or hydrothermal fluid seeps through the hollow cavities, chemical precipitation begins to fill the hollows from the outside in, often forming concentric layers.  Geodes commonly have a cryptocrytalline quartz shell lined by various other minerals like calcite, pyrite, celestite, and macrocrystalline quartz, often in crystals visible to the naked eye.

Some Agate Geodes mined in Brazil are dyed using a 19th-century process developed in Germany.  Agate is relatively porous, and this process, which involves heating the agate to a high temperature, allows the dye to be absorbed throughout the rock, not just on the surface.  Usually agate without much natural color or pattern is selected for dyeing.  The purple, blue, pink, and teal Brazilian Agate Bookends on this page have been dyed using this process.
