Silver or White Brass?

[Escwilson]

I was told this might be white brass but I thought it was silver even though it isn't stamped with .925. Does anyone know? It's heavy and does not stick to a magnet. The only marking is the one in the picture. I can't even tell what it is to look it up. I hope I uploaded the pictures right. Thank you

I am guessing pot metal. You might need to get a silver test kit or take it to a jeweler but I doubt it is silver.
