I guess is due to the relative distance from the camera. Most of the time the earrings are closer to the camera when taking photos, hence always look bigger than the pendant even though they are exact same size.I wonder if it because the lobe is relatively small compared to the earrings vs. the relative expanse of your chest ratio to the earrings. I think unless you are super tiny it tends to look puny and might explain why the small looks good layered with other pendants
