Nice design, great green! (I love those little multi-coloured checkerboard diamonds.)
It doesn't look Turkoman to me though, at least not old. Could it be something else tribal?
The outermost border is Tekke-based, the third one in is Ersari, but the rest is all sorts of things, as you find them on Balouch rugs for instance, but also some Caucasian motives, I believe.
