Hi Nick,
It is 5,3 x 7,4 cm. It is definitely not a miniature. That means 5,3 cms in diameter. What do you think about number of rays? It has 8 rays. Normaly lover classes have 4, 5 rays, higher classes 6 rays. I have never seen a badge with 8 rays. And another thing. The colour of the stones. Green central rays and purple mini-rays between.
Any usefull info on this piece? Perhaps Lady variant? Like al-kemal of egypt? Or Pleiade badge (seven sisters) Pahlevi persia?
Mat.
