Rare and so hard to find, this is a gorgeous Pre Ban Tortoise Shell Bangle from the early 1900s. These bracelets come with a slice cut so they can be pulled apart slightly to fit over wrist. The thing with these is that you don't really want to pull it much at all, getting your hand and the inside of the bangle lubricated with soap or lotion allows it to slide right over your hand very easily.
Bracelet measures .9" wide, inside diameter is 2.18".
Tortoise shell is usually from the shell of the Hawksbill turtle. Hawksbill shells slightly change colors, depending on water temperature.
