If I dated a man that turned out to be a drug addict and he stole a diamond ring from my jewelry box and my car, can I take him to court?

My car was found a few weeks later in a port, however he got away. I have the police reports. My ring was never found, and I he later told me that he didn't pawn my ring in a pawn shop he gave it to the drug dealer so I could not get it back. He is now sober and he promised me that he would pay me back for the damage to my car, impound fees towing costs and for my ring. He has not yet paid a dime. He now owns a business and striving just bought new cars and a boat. I again asked him for the money he owes me and he refuses to pay me.
