This is a hand made crucifix. The complete crucifix is made with brass casting and then polished to give an Antique Tone.
A Crucifix: (from Latin cruci fixus meaning "(one) fixed to a cross") is an image of Jesus on the cross, as distinct from a bare cross. The representation of Jesus himself attached to the cross is referred to in English as the corpus (Latin for "body"). (source: https://en.wikipedia.org)
