My Treasured Possession by Ella

It shows me when I am sad, it shows me when I am happy. I can't tell when it changes, but when it does I'll know. Sometimes it is dark blue and sometimes bright red, it all depends on my mood. It's made out of round shiny silver metal that glitters in the sun. I wear it on my bony little finger, though it may slip. On my finger it will show my emotions. It sat there silently waiting for me, for it to be worn upon my finger. It suddenly changed colour and I bought it straight away.
