Well first of all, you aren't giving any indication that you saw the words "Arabic Script" in my message, so i'm going to presume you didn't notice it.
Arabic script does not look like our writing, it is very different, and unless you already know how to read it, lets just say most Americans see it as a bunch of squiggly lines. Like this: " علم المملكة العربية السعودية ".
I happen to know that the Saudi Arabian flag contains the exact same phrase and it's written in Arabic Script. Now I don't know if it's in some sort of "High" Arabian script, or ordinary Arabian script, or even if there is a difference, but here is what the shahada ( Islamic declaration of faith) looks like on the Saudi Flag.
How does that compare to this?
Well I don't know, because I don't read any version of Arabic Script, but according to the linked article, those people who claim to be experts say that the ring says "There is no God but Allah".
