Am I doing too much?

So I let my sister borrow something expensive. I usually let her ho my things but I only wore thsi one time so I didn’t think much of it. Fast forward to me packing for school and I ask for the item back. She tells me it’s on the dresser. I go look and all the items on the dresser are pretty much unusable so I assumed it wasn’t mine. I ask her where it is and she says “if it’s not up there then idk”. So I ask for my money back at least. She ignored me. I ask if she knew where it was. She ignores me. So I’m current waiting on a response I know is not coming about my item because I need it now. She said she would pay me back but I need to know when so I can use the money but I don’t think she is. Should I address it once more? I don’t think she really plans on paying me back
