The purpose of this report is to describe a second investigation of a large group of 13 statuettes made of stone that we have identified by EDAX, x-ray diffraction and scanning electron microscopy as rich in dickite, a ubiquitous clay material commonly found in the region of the Caspian Sea. These artifacts are unprovenienced of questionable authenticity, and highly controversial although being bought and currently exhibited in American museums. The methods that we have used to establish their authenticity include 1) by scanning electron microscopy, experimental duplication of pattern of drill marks found on all the artifacts in order to determine if they could have been made with a contemporary drill or an ancient one; 2) a cross-sectional analysis of the drill holes to determine if they were made with a rotary drill or a hand-held borer showing incomplete rotation; (3) experimental stressing by alternating application of physical, chemical, and thermal means to duplicate the pattern of fine fracture lines present on all the artifacts; and (4) thermoluminescence to determine if and when the pieces were subject to thermal changes.
