chain with captive shell

Shell Captive:

One of my craziest endeavors yet: a tiny shell (about 1/4 of an inch long) contained in a fine chain of Turkish Roundmaille.  The chain is about 2 1/2" long.  Unlike its larger relative, the Tigerseye Captive, this is still in one piece and resides somewhere amongst the chaos of my desk.

Rings:
26 or 28? ga. wrapped around a length of 14 ga. wire
Brass
24 ga 5/32" ID
Sterling Silver
In the Turkish Roundmaille weave
