By watching jewelry selling channels it teaches you about how lighting and the color of material under the stone will change it's color. PJ --Previous Message-- : Hi, : : I am of the opinion that it is an Emerald. : Light and the colour of the cloth can change : the colour. Even though the Emerald is a : large stone from the front I am not sure : that it is a very deep stone and thus : perhaps more likely than some to change hue : on different coloured outfits. : : We also need to think about the Queen : Mother. She had not fondness for amethysts : and in her generation they were associated : with half morning. She did sell a parure of : amethysts at one time. : : : : --Previous Message-- : I have looked again at the video of the : christening of Prince Harry and, although at : times the central stone in QEQM's brooch : catches the light, at no time does it look : like the emerald. The central stone seems : not only opaque but to absorb light. : : : : : : When I initially commented in September, I : assumed that the stone was an amethyst but : an amethyst would refract light and show : some purple tones. This stone does not. That : is, in my opinion, clearly highlighted by : the video where we can see movement. : : : : I wonder if the dark stone, which some of us : are intrigued by, could be either a black : sapphire or a black diamond? Both stones : absorb light. : : : : Having said that, I have never personally : seen a large black diamond, only small ones. : A black spinel is another possibility. : : According to the press, Mrs Greville owned : black diamonds, although I have never seen : press reports of her wearing black diamonds : to various functions. : : : : : : : :
