Reply below. Acquired pre internet era as a collectible antique "Victorian" snake motif "wooden" bracelet which now appears to be a Black or Gold Coral branch bracelet carved crossover bypass bangle in snake motif, yet resembling carved Mississippi mud bakelite in color and swirls.
Also sometimes called "Gold" and can be almost black in color. It has an ethnographic "Easter Island" odd look snake appeal as well.
Initially it looked more like dark wood, or Mississippi mud bakelite, yet when louped the "knots" where the coral spines or branches may have originated were found to be numerous! See extreme closeups and you decide.
Bangle like bypass interior with a tiny 2 - 5mm give is 2 3/8 X 2 1/8" oval.
Look for mid century same material screwback hoop earrings images 3 -5.
Don't let the low price deter you choice, as these can be found elsewhere at double or 3X this! A very good buy, with plenty of room to resell.
$12 USPS Priority/Ins/Track or Free with your USA Ck or USPS MO.
