After moving back up to New England, I've been bouncing around to different places looking for some more historical stuff. Found this ring this weekend about 100 feet from where I was fortunate enough to meet worldtalker today!
I didn't think so when I pulled it out, but later inspection shows that it has been resized. My bride was able to find the slight hint of a "k" marking, but we can't make out if it's 10 or 14. Also, this was 3 inches deep and caked with dirt and roots. It would have been in worse shape if it was costume.
