I googled the latin and let google change it to
"pax aut bellum justitia universalis "
The original is gone but I tried the cached page and found a couple of symbols you might recognize. (It's in Danish, I think.)
Does the ring have the emblems from this page?

It appears to be part of the I.O.O.F. The International Order of Odd Fellows. A society like the Elks, Masons etc. The 3 link chain is the symbol used by the IOOF guilds I have seen.
