Ugh I see some of the lettering looks like Hebrew as well as the blasphemous binding circle. If you're looking for something to use as a pendulum try to find something better, natural crystals are pretty good.
Well, it says LaVeyan in the description, and Anton LaVey was ill-informed (or careless) enough to use Hebrew characters in the insignia for their "church."
So I would say it's Hebrew.
