2. Ring Finger - This is a Tiger Eye stone - not sure if the setting has a specific name or not, but it looks gold.
3. Pinky Finger - silver Iron Cross ring - this is probably going to be the easiest to find if you're not super-picky - I've even seen them at Target in the past.
In this photo, the Iron Cross ring looks like it has a skinny band. You can also see a knot (?) in Eddie's slingshot rubber on the back of his neck.
ETA - Steve V. found an incredible match for the Iron Cross ring. He said it was listed as "Franco-Prussian war silver iron cross ring". Under the black enamel there is a crown and a date.
