You could say that there are 19 artifacts, actually. There are two versions of Hiricine's Ring, just like there are two versions of Azura's Star. The two versions look the same, have the same name, but they do have different effects. There's the 'cursed' version that will make werewolves transform at random, this is the version that you originally get from Sinding, and then there's also the 'reward' version that you get if you side with Sinding that has the effect of allowing werewolves to transform twice a day. So, yeah, 19.
