What markings tell silver content?

[dustbuster]

I was just wondering if I was reading the markings on a ring wrong. I believe it says 925, but could it be something else? It is fairly tarnished and maybe it is plated, not sure.
Sorry, no pics. No camera at the moment.
Thanks,
Dustbuster

925 = 92.5% silver = Sterling

Thank you. Thought maybe it may have been another meaning like plated or something. I know that the stone must be cz. This was my first silver ring. Mostly finding kiddy type rings.
