hopefullgold,
The details you need about your rings will be stamped on the inside of them. If no markings then only costume jewelry. Also put a magnet next to them to see if it attracts them, if so then costume. Job well done though as you detected them and got them back out of the ground and that is always good for a rush. Hope they are silver or platinum or even gold would be ok.......................63bkpkr
One on the right looks like stainless steel... The one in the middle looks sterling, the on on the left looks copper.... The one with the stone also looks silver ! Others are right, check for markings and those should tell you... If not marked then likely costume stuff....
Keep @ it and HH !!
I tried the magnet on them. The one ring with the diamond had a slight attraction to the magnet at the bottom of the ring. It looks as if it had been repaired or resized but the rest of it does not attract the magnet. Also no markings on any of the rings. I think one might be silver as it has some weight to it. Not sure about the diamond ring until it get it checked out. Oh well not bad for my third time out at my local park with a new at pro.
