Tungsten occurs naturally on Earth. It is expected to have been produced by the same supernovae that produced our other heavy elements. It was first identified by Johan Gottschalk Wallerius in 1747. There are mines in Europe and China that produce most of it. A few mines in North and South America. I hope I guessed which "origin" you intended...
