Definitely one of a kind, due to the process!
16" snake chain. 
pendant is 1.25"  top to bottom and 3/4 " at widest point.
hallmark is on the front.  
 
The "splat" was made by pouring molten silver into a tub of water.
Not all the silver comes out of that fizzing process as a nice shape and mostly has to be re melted. Sometimes though, I get a fun shape, and this is what I made with it .
The back ot the pendant has a shiny heart shape floating inside a texured surround..
