Gemstone bead elastic bracelet w/ A initial charm jewelry

Bracelet is in good condition and kept in a clean smoke free home. Tested in the tourmaline category on my gemstone tester. It looks like white turquoise and may be. Turquoise is not a:stone that my tester tests so it will land on closest composition. It’s definitely a gemstone. Initial A charm can be removed, 26mm round flat , not sure of metal. Sits at 6 1/2 before stretching. Each gemstone bead is approximate 11mm round, wire with brownish/grayish veins. #gemstone #Jewelry #bracelet
