Wavellite was discovered in 1805 at High Down, Filleigh, Devon, England. It was named after a local doctor William Wavell M.D. who brought it to the attention of the mineralogical community. It is translucent and can be found in blue, green, yellow, and white colors. Specimens can be stalactitic or the crystals can radiate from the center creating a spherical structure. Many notable specimens are found from the Ouachita Mountains in Mount Ida, Arkansas.
