Yes. Your mother can always call the police or make a police report stating that you stole her jewelery, and the offense would be a larceny (whether or not it would be a felony or misdemeanor usually depends on the total value of the items stolen). In your case, your mother however would have to want to press charges and agree to testify in court against you if you decided to go to trial on the matter. Often times family disputes like these get dismissed because the relationship is mended and the victim no longer wants to go forward with the prosecution, but yes, your mother can still pursue criminal charges at this point.
