Industrial small sculpture, Tower is as symbolic as most of what I make.
The tower is not a prison but a small lighthouse with a "small boat" aside that holds a small labradorite stone. With a complex wide band, the adjustable side is at one of the sides. As is it fits a finger size 8 1/2 to 9 and could be extended to a bit more than a size 10.
Fun, Tower has a small tag inside tied with a chain link to its interior that comes out "sometimes" and makes a soft rattle like sound. 
-Sorry for the light in the video, had to make them with artificial light. :( -
