Trying to ID manufacturer, metal and stones.

Bought this on a whim. There are no markings that I can find. The right lid is a little heavier than the left. I used a strong fridge magnet and it was non magnetic but I did get a small amount of resistance. What really excited me was the ice test. The cube melted right away. In one of the pics you can see a part of the foot has broken off and to my untrained eye, looks like silver. I'd like to sell it but don't want to get ripped off . How can I tell if it's a) real, b) the purity, c) the best place to get the most ie pawn shop, LCS, ebay etc? Aprox 42oz on my kitchen scale. Apologies about my potato camera.
