Vintage Bangle Bracelet, marble wood looking

Vintage Bangle Bracelet. This is an interesting bangle, it is very lightweight and looks like wood. But I cant really tell if it is wood or not. It also has some marbling which could be to make it look like wood or maybe it was supposed to look like marble. Either way, its unique. Still in good condition, some minor/common pre-owned wear, please refer to pictures
