--Previous Message-- [snip] : In the photos supplied by Joye the Duchess : of Kent and the Queen Mother are wearing : different brooches (and I suspect we can see : a shadow rather than pendant drops under the : brooch worn by QEQM). The brooch worn by the : Duchess is commonly identified as part of : the demi-parure so I think we can identify 2 : of the brooches. [snip]
I think that it's due to the blurry picture of QEQM that the pendant drops look like a dark shadow. Darker colours tend to "leak" in a grainy picture, hence the "shadow" looking bigger than the amethysts actually are. I'd say the brooch in both photos is probably the same.
Regarding the two remaining brooches I agree with Arthur - the two elements in the necklace and the brooch are just too similar in size and shape and design.
