Maker of unique glass jewlery/vials?

My friend’s 16th birthday is comming up, and I figured it’d be really neat if I did something unique for her. She’s a huge Naruto fan, and her favorite character is Gaara, so what I wanted to do was possibly have a glass necklace of Gaara’s gourd made, and fill it with sand so she could wear it.

Does anyone know someone who could do this, or a shop where I could buy an item similar to it? Or, if no one knows either of those things, could someone tell me how much it could end up running me if I ended up having it custom made? I figured the vial would be an inch, inch and a half long, max.

Any help would be much appreciated!
