A long time ago, cloissoné fish like this one were sold as trinkets in Chinatown. This is my cast and fabricated sterling version sans the enamel. 
Cast sterling silver head and fins with mill patterned and fabricated body,  and all parts woven together to create a  kinetic fish,  on a 16" 5mm rubber cord with sterling  lock and twist magnetic clasp (shown).
$375.
