The silmarils were made from a new unique material. My guess is that the arkenstone was some of that material, but not a silmaril. It does have the power to capture the light from the undying trees, as it glows on its own, but it is not a complete silmaril, as all of them were lost in different places.

I was waiting to watch to see what people were saying. Did they really say that in the show?
