(Possibly faux) Yak(?) Tooth Carved Necklaces

[DeadMenTellNoTales]

So my family went to this woman's house who wanted to get rid of stuff the old owners left, and these were in there. I think they might be faux because there was also an elephant one in there from the Animal Social Company. Any ideas what these might be worth/who made them?

Looks very similar to this - right down to the knot and bead.
