It is cast in white bronze, it is a hollow cast and has a comfortable weight of 20 grams. The chain is strung through the skull, as the piece would bounce around too much when hung from a jump ring.
The darkened or gold tone brass chain comes in the length of your choice. It has a brass round clasp, which is delicate enough to clasp into any of the loops for wearing the chain as short or long as you choose.
Please specify whether you would like a black or an antique finish.
