The bottom-most aspects on the ruby (the primary pavilion aspects) attract their light from the highest possible angles. When a Hearts & & Arrows ruby is photographed from straight overhanging, these areas will go dark if the camera obstructs, or obstructs, the light. This is called blockage. The dark areas are, essentially, a representation of the viewer or camera lens in the crown of the ruby.
Not unless you work hard to do so. The only means blockage could be seen as it appears in these photos is if you have the ability to hold the ruby perfectly still while blocking the light with your head at the right distance. When diamonds are unobstructed (almost all the moment) the patterns are not obvious.
