The reflection can be either external (e.g. without the light passing through the crystal) which contributes to the parhelic circle near the Sun, or internal (one or more reflections inside the crystal) which creates much of the circle away from the Sun.
The phenomenon in question can manifest as an external occurrence, where no light passes through the crystal, resulting in a parhelic circle nearby the Sun. Alternatively, it can arise from internal occurrences, involving one or more reflections within the crystal, which then generates most of the circle at a distance from the Sun.
