Thank you to everyone that left a comment and tried to help me.
Today I went to the police station of Sliema and, obviously, they didn’t have my necklace, because it is expensive and nobody would ever give it back.
I think that whoever took it did either sell it or keep it.
I can’t do nothing if they want to keep it BUT if they sell it in some jewellery I could buy it (kinda ironic I know).
I’ll try contacting A LOT of jewellery/places where you can sell and buy gold.
An important friend of my parents will go to the police headquarters and see if they can send the photo of my necklace to all the jewelleries.
Sorry for my awful grammar english isn’t my frist language and I’m still learning.
