Interesting Blue Beaded Bird Ring - Size, not sure…maybe a 5.5? Or a size 6?

I love this ring but I used to be able to wear it on my index finger. I thought it was bigger than a 5.5 because I was never able to wear it on my ring finger…Now I can wear it on my ring finger. It is a little big on my ring finger…So I am guessing it is either a 5.5 or a size 6. Beads on the ring are a pretty light turquoise shade.
