Odd stamps : 08 Stamps with special cuts - 03 a

In this next round, I am taking you to the world of diamond shaped stamps.
I do know that squares are diamonds as well, but i will only show you diamond shaped stamps, where one of the angles is pointing downwards, in order to see the design of the stamp as it was ment.
This means that I'm not turning any common square stamp to make them look like diamonds.

Let's start with some examples from Asia

Mongolia :

Nepal :

China PR :

Japan :

(non officicial) Molukkan State :
