Well, I am not sure about which monastery this coral Dorje Shugden belongs to but I can see the workmanship is very refined. I like the fact that monasteries can practice Dorje Shugden in the open without the fear of persecution as in the Tibetan community of India. There, the Dorje Shugden means nothing and although they are very devoted to the Dalai Lama but they know where the lineage originates.
Anyway, here's a list of monasteries in Mongolia, of which one may be the one that is the custodian of this exquisite shrine to Dorje Shugden:-
