My most precious possession

This is my favourite necklace.The necklace was my birthday present when I was 15 years old.This lets me think about last time when we are having fun together with friends.Now,we go to further study.All separate in different places.I like the necklace very much.Last time,my friends know that I like to wear necklace.So,they buy that necklace as a present to me.That's all about it.
