Given the color of the background, a 1/4 Lambda plate was used. A Lambda plate would produce a bright magenta background-color.

Nathan, they are about 0.5 mm across

This example is a flatter crystal

When I say a Lambda, I really mean a home made phase plate out of plastic. I also rotated the top polarizer slightly as it transitioned from magenta to green and found a more neutral colour and then did white balance in the camera to remove off colour.
