This is called a cuff style bracelet and I agree pic is hard to tell...but looks it also has a catch chain which you don't see on a small child's bracelet very often. The bracelets are typically solid or slip/bend style.
I would like the dimensions.
The coral was used during that time line. Don't believe it is pearl...but it could be opal. Can't tell from this pic. (Hope it isn't opal, if it hasn't been oiled over the years it will disintegrate if jostled too much!)
