Crowley's Ridge Agates were found as river-worn pieces in the floodplains of Mississippi River near Forrest City, Arkansas and the hard limestones of Crowley's Ridge is said to be the source of those lace-like agates. Some agates may be found in Mississippi, Missouri and along the Mississippi river all the way to Louisiana. The colors are typically dull yellow to tan and widely fractured, but good specimens have been found with great banding details and sometimes with rare pinkish colors. Some agates would look best if left in their natural forms, some look best if contour-polished, some looking best if oiled (ugh!), and others looking best if cut.  From time to time, they can be found along Crowley's Ridge tracing to the lace-agate and quartz site at Washington county while loose pieces were spread throughout the river basin of Mississippi river (Mississippi and Louisiana are examples). Some pinkish-reddish hues on some nodules may be a result of wildfires(???).

Some people "bath" them in mineral oil to show more details.
