Multi Strand Red Coral Bead Necklace

Found in scrap bag. Four separate stands of small coral circular beads. Each necklace is a different length, and when all worn together makes look like a quadruple strand necklace. No clasps on them, but clamped off at the ends. Weighs 101 grams total. Did a Acetone test, if it’s coral it’s not dyed. Also submerged a section in white vinegar and got a reaction.
