To Hans: The maximum I can do is these two photos which were already posted in this board recently. As already mentioned, this brooch is an element of the tiara, which can also be worn as a necklace by mounting the leaves on a diamond chain. All these photos are from the book by Reginald Davies, "Royal Families of the World". Talking about the colour of the stones, I remember that at a closer look this pendant (the leaf above) had a nice looking emerald green colour, the opposite of the dark green we see when the tiara is completely mounted.
