How to use "earring" in a sentence

It was a blue earring, and I remembered exactly where I had last seen it.

I couldn't think of an answer so I took the blue earring from my pocket

'Lettice,' I said, and held out the earring, 'Why did you drop this in my study?'

Because the last time I saw, this earring was on Friday morning when I came to Old Hall with Colonel Melchett

I hoped it would get her into trouble.' I told her that I would return the earring to Anne and say nothing about how I had found it.

But when she had found nothing, she had dropped Anne's earring by the desk.
