Would the police get involved for an expensive stolen object by a minor?

My mom bought me glasses($400). They are "real" and the lenses are made to fit my eye vision. I'm in middle school and a high school boy who has a reputation for stealing things (ipods, iphones etc) stole my glasses while he was hanging out with me. Will the police be willing to get involved in this? I live in California. I really need them back, they're expensive and I can barely see anything during class… Or life

Can you prove it?

Well yes he is in high school (i don't know the age but i guess 14-18) and he is the legal age to get charged you know who he is report him and to this guy if he wants something he better get his *** off his bed and work and grind like everyone else. So yeah the police will get involed
