sniffing out the silver between pulltabs. Swastika ring very old judging by the engraved cursive script. Engraved " Greda" . Creepy ring. Just hope it was made with new silver. Not recycled silver if you know what I mean.
You mite do some research on the area that you found your ring. Before the Nazi times, the swastika meant good health and good wealth. I recently saw some old heaters with swastikas on it and immediately thought Nazi. But after curiosity hit me, I looked it up on the web. Silver is silver and if it creeps you out then sell it, in sure there's people out there looking for such items.
The items with the swatiska on them are becoming collector items as after WW2 most of them were melted down and or destroyed. Especially the Nazi coins. As stated above the original, several thousand years old, symbol was for good luck.
Another note is, the so called swastika was used hundreds of years before the Nazis as a symbol of the "four winds" . Very common in the Plains Indian and Navajo cultures.
Another forum pointed out (and I took note) that if it is laid out square like the above coca cola one, then it's not nazi related but if it stands on a point like the ring then it is nazi related. No expert, but I thought I would relay the info I learned
