AITA for using my grandmother’s china after my mother said it was display only?

My grandmother left me a set of floral china because I was the grandchild who cooked with her. My mother helped pack it and said, “These are display pieces now. They survived seventy years.”

I never agreed to that.

For my thirtieth birthday, I used the plates for dinner with six friends. I liked seeing food on them instead of looking at them through a cabinet door. Before anyone arrived, my mother stopped by with flowers and saw the table.

She asked me to replace every plate with my everyday dishes. I said Grandma used them for Sunday lunch and would have hated turning them into museum objects.

During dessert, a friend chipped one plate against the sink.

My mother cried when she saw it the next day. She said I had confused inheriting an object with inheriting the right to erase its history. I said ordinary use was part of that history.

The friend offered to pay for a matching replacement, but the pattern is difficult to find. My mother does not want a replacement. She wants me to promise never to use the set again.

I have not promised. The chip is small, and I still think the plates should be part of meals. Yet I cannot dismiss that my choice gave my mother a fresh loss connected to her own mother.

I own the china. That answer feels legally complete and emotionally useless.
