Day 245 - Big blingy crystal ring

I really don't know where this is from!! I don't really wear it much as it is quite bling-tastic but its still pretty and the back is adjustable which makes it a great piece if you tend to change with the seasons, shall we say! My arthritis in a couple of my fingers means I can find at some times of the year my fingers are a whole size bigger/smaller so having something that is adjustable is a real help.
