woohooo!!! 你 can get the official H2o locket here... link
Very rare and hard to get hold of.. sold out everywhere.
Its a replica of the locket (with moodstone) that the 《美人鱼》 wear in the TV 显示 H2o Just add Water and is an official licensed product.
The 项链 is great quality. It is a highly polished stainless steel 项链 that looks like silver. The locket opens and has three pictures of the 《美人鱼》 to put inside (or 你 can use your own photo).
