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