Family jewelry given to bride should be returned to groom after divorce

Hello everyone, Here in this forum we all talk about the most laws in are in favour of the girl and wives but what about the situation of the Boys and Husbands? In this case I would like to have some legal advice and your response. This meeting was in arranged by the parents and the boy and girl agreed to get married per Hindu tradition after about 18 months. As per family tradition at the time of wedding Grooms family gave her engagements ring, wedding ring, lots of jewellery and about 80-100 years old family jewellery also. There was no dowry given or demanded by the groom. The Groom and the bride live in different cities. At the time of their honeymoon the boy caught the girl on phone with her boyfriend and overheard their intimate conversation. Upon asking she admitted that her affair was going on since few years and as the boyfriend did not earn much, her parents forced her to get married to this boy. She agreed to behave but still carried on meeting her boyfriend and never joined her husband in other city. As the girl did not want to join the husband and started fights, the groom filed a divorce. The girl and her family kept all the family jewellery and are refusing to return it to the groom’s family. Now here is the question:- Are the groom and his family entitled to get the Family jewellery back? A few such case Judgments references and case numbers are appreciated. Thanks
