There was, however, a description of 5 of the emeralds.
But what is the shape of the central stone in the Pembroke tiara? Every photo I have seen suggests a different shape to me. And is the stone an emerald?
It also seems to me that none of the Bavarian stones, except for the one described as "a cabochon emerald drop", is large enough to be the stone in the Permbroke tiara.
