Is the script on the official The One Ring, Black Speech, or the elvish translation of the One Ring poem?

It is the Black Speech! All our officially licensed The One Rings (silver, 10K gold, and gold-plated tungsten carbide) feature the Black Speech. We can custom engraving of the elvish script, for example, the English version of the One Ring poem on our Jens Hansen Elvish Inspired Wedding Rings. (what we also call the Movie Ring)
