i should also mention that the dark purple one is all nice and smooth and the lighter purple is more crater like

Some are faulty. I had a red and a purple one like that, they donst have such a nice texture as the regular ones and I dont know how to fix it, so I poured them in a lunar and when mixed with the others it doesnt show anymore.
