AITA for not giving back my finances deceased grandmothers engagement ring?

Throwaway account. I 29 female am engaged to Jake 32, male. We have been engaged for 2 years. He has an older brother, Sam 38.

When Jake and I got engaged Jake wanted me to have his grandmothers engagement ring. Jake talked to Sam and Sam said since he doesn’t plan to get married or have children that Jake should use the ring.

I love that ring and love the sentimental meaning behind it. Sam met a wonderful woman, Hannah, within the past year and they are expecting a child. Once they found out it would be a girl Hannah told Sam she wants him to get the ring back for their daughter.

Jake has already told Sam no.

During Sunday dinner last weekend at my mother in laws house Hannah brought up the ring and how it should be given to their daughter since she would a great grandchild and I am not related by blood. It became an intense discussion. Luckily my mother in law also agrees with my fiance and I.

Hannah then asked if her daughter could have it in our will. I said no because it will either be given to our son or our future daughter. I told Hannah to take up her problem with Sam since he’s the one who let Jake have the ring to give to me.

Hannah ended up leaving the house crying. AITA?
