Silver 925 JPI Bracelet Hinged Clamper Bangle Purple Black Textured

Unusual silver bracelet. It features squares of purple and black. May be onyx or enamel, I can't say for sure which it is. It has a spring hinge that opens at the side. The inside is a wide mesh. The inside is marked JPI 925. Good used condition with some wear due to use including some scratches.
