Very rare and hard to get hold of.. sold out everywhere.
Its a replica of the locket (with moodstone) that the sirene wear in the TV mostra H2o Just add Water and is an official licensed product.
The collana is great quality. It is a highly polished stainless steel collana that looks like silver. The locket opens and has three pictures of the sirene to put inside (or te can use your own photo).
