Crystal Bay isn't in Bali but between Nusa Penida and Nusa Cenida, two islands on the east of Bali
Both Nusa Penida and Nusa Ceningan (not Cenida) are part of the province of Bali: the inhabitants speak a version of Balinese and are culturally Balinese, and the dive sites are considered Bali dive sites. Crystal Bay, for the record, is a bay on Penida island. Yes, they are islands: but there are lots of islands that belong to Bali (like the Gilis - both the famous three and other less famous Gilis - belong to Lombok).
