I am millions of years old, yet I am just 37 – add one to me and you have the Earth; take one from me and you have nobility. I am common; indeed I rank 23rd among my five-score fellow inhabitants of your crust. Yet I am special, lending a blush to your celebrations, and giving the finest of temperaments to your clocks. I am hard; yet I melt at your touch. I first came to your notice in 1861, discovered by he who gives his name to the burner - yet I did not bring prizes to you until 2001. Can you name me?
