A typical set of prison tattoos called ‘rings’, specific to Post-Soviet criminal underworld.
There are various types of rings, and each of them has a specific meaning.
Here, the rings stand for following things:
1(left) - ‘Otritzalo’. Basically, a status ring that means this convict will never under any circumstances cooperate with prison staff or law enforcement in general.
2(middle) - Anybody who has been in jail at least once can get this tattoo. It basically means ‘convict’.
3(right) - traditionally, it’s an S-shaped snake crossed by two bars. It means the owner has served two terms in prison.
It is also curious that this person obviously used to have a tattoo on his far right finger, too, but all that remains now is a scar. We will never know what kind of ring he had there…but it was most probably nothing to be proud of.
