Fossil Ammonite on Oxidized Sterling Silver

This is a fossil ammonite that was alive when the dinosaurs roamed the earth.  That makes this roughly 240 million years old.  It is havd wire wrapped on oxidized sterling silver heavy chain, and finished with tigers-eye beads, and a heavy toggle clasp that is worn in the front.  The length is 26"

The length can be changed if you need it shorter.  This one can not be lengthened.
