Just wondering what the collective thinks this is.

A friend of mine had it sitting on his cupboard with a mixture of odd rocks. He found it in his youth somewhere in Central Australia.

It is definitely not as dense as ironstone or a meteorite, it weighs 72g.
I couldn't find a measuring cylinder tonight to work out its volume and actual density.
Its shape is almost two perfect 29mm diameter spheres joined together, with a bit of a lump on one side.

Surface is generally smooth to touch.

I thought it might be a tectite but haven't seen them this shape before.

All serious comments welcome.
