One end of a rod projects upward through an opening disposed at the bottom of the reservoir, the rod adapted to slide along the opening, and having at the one end a concave indentation facing upward and shaped to support one of the stones. Connected to the other end of the rod is means for sliding the one end of the rod between a first position within the reservoir, and a second position outside the reservoir, whereat the one end is positioned exactly within the field of view of an objective of the microscope such that a stone supported by the indentation is disposed precisely at the focal length of the microscope objective.
