Husband taking back jewellery that was given to the wife

I wanted to ask that my husband divorced me after my mother in law passed. I have a baby girl in this marriage. My sister in law and my husband took away whatever jewellery my mother in law gave me at my wedding. I have a two and a half year old baby girl. Please tell me if it is right in Islam to give something and take it back because at the time my mother in law gave me the jewellery she said it's yours. The jewellery was with me in my cupboard since the day I got married and when I went to take my belongings from my husbands house, they asked me to give me whatever gold jewellery my mother in law gave me because my husband said that if I don't give the gold jewellery, he will not give me a single rupee for my baby's expenses.
