Switching Viewing Platforms:

This microscope comes with two distinctive viewing platforms. One clear translucent platform that allows diffused light to enter to enter from below. The second disk is white and not transparent. This stage allows for maximized contrast when viewing a stone.

Once that is complete insert the stone into the stone holder then affix the stone holder to the base as shown in the picture below. Next, turn the power switch to the on position by pushing the power button. Adjust the eyepieces to fit the width of your eyes and then observe.
