I can say that I have never seen a KM style jar that is black in color. The closest I have seen are the KM vases that have the black colored cellophane type stuff to make the vase look translucent black, more of a gunsmoke actually. (EDIT: Aww snap, I found one by temsaah)
This vase is black with mostly silver motif http://www.hookahstore.com/accessori...base-p-86.html
, not bad.
here is what I see picture as the base you want. I would call HookahCompany up and ask about getting it separately, they are an absolute delight to deal with in my experience.
