Thank you, Baxter, for your pictures. They show that the two brooches, not only have a different shape, but also a different colour (on the B&W pictures, the kunzite looks paler than the other darker stone).
Nellie, I also wondered if Queen Mary's unidentified brooch could be the central stone of Empress Maria Feodorovna's sapphire tiara. But I think it is probably not, as the central sapphire in this tiara has an oval shape, whereas the stone is QM's brooch has more of a square shape, or cushion-shape.
