History of Famous Jewels and Collections: Re: Queen Alexandra. Velvet and diamond choker/s. One or two?

It looks like two different chokers to me, especially in the Getty Images.

I think that the photos below show the same velvet and diamond choker, but in one it looks as if the motif has been set vertically instead of horizontally. Are my eyes deceiving me because of the poor quality of the photos? Are there 2 very similar chokers or just the one?

I also have in the back of my mind that this choker was inherited by Queen Maud. Or am I imagining that?
