To bead this choker, I did netted weave using bright green, bugle beads;  gold and purple, size 10, seed beads; and  gold tone, Indian, dancing bells.  

Because I added an extender, the length is adjustable; starting at 31 cm. (12 1/2"), up to 47 cm. (18 1/2"). 
It closes with a gold tone, lobster claw clasp.
If you would prefer the tail looped up rather than dangle,  just let me know at time of purchase;  and I can easily add a hook at the end. 

The last photo shows more of my work.  
If you don't see the listing in my shop, contact me and, chances are, if I don't have it in stock I can probably make a custom necklace for you.

This is a simple version of the amazing collars made by Native-Americans, for centuries, up to the present.  
To see some examples, go to the National Museum of the American Indian (NMAI), and search under beadwork/netted weave.
