Repurposed, Readymade Decorated Shell Necklace

After receiving this metal alloy (unknown silvertone composition and small brass beads) necklace as part of a collection of unwanted jewelry and components, and seeing and almost hearing shells clamoring for more, Amy added her distinctive artwork to three of the six frames.  The necklace is comprised of great curved shapes, graduated-size, two-toned, ball beads, and a screw-in clasp.
Necklace: 18"
