Pueblo and Bullets is light in weight with a bonded leather thick neck piece and a couple of surprises in it. The focal construction has an artifact set  in solid fold formed copper...  an authentic ancient Pueblo tribe -Anasazi- pottery shard, they were a prehistoric Native American civilization that existed from approximately AD 100 to 1600 and who's pottery is even today almost a mystery since even when very thin was strong, durable and totally functional and it is really really hard to even Try to reproduce it. The other surprise is how it is finished: The bonded leather ends in two bullet cases with a bail that works to connect the chain holding the bail and clasp eye. Yep, real bullet casings... 
The pictures where the piece resting on a bust show how long, bold is since it is a normal human size mannequin.
It measures as is around the neck approx from 19 to 20 1/2 inches depending on where in the back chain you clasp it. It can't be reduced.
