~ the ring that opened the topic!

Nutmeg,,from these photos I believe your example is a good one..

Sure,SS soldiers could have wore it.. Actually, anyone with the cash could buy and wear such a ring.. Money was hard to come by pre war and wartime so it wasn't bought as a goof or to waste..
Most were bought by the soldiers themselves. Many were bought by wifes or other family members for a soldier as a present.
These skull rings were popular with SS, Panzer and the HJ,,,and really there are photos of all the 4 main branches of service [Heer,Luft.,KM,SS] wearing skull rings..
Also in many of the period magazines for the armed services and para-military organizations you'll occasionally find advertisements for such pieces...

The victors of the war [the Allies] were also fond of these rings and took many back home to wear and/or show off to friends and family,,,
