Franck, I am assuming you have a small typo when you wrote "Queen Mary".

I am hopeless at judging the size of diamonds in the various necklaces and gauging which necklace is which unless there is a big difference in diamond size.

So with all of my limitations --

Below is a sketch showing the necklace given by the Crown Prince and Princess of Denmark and the one left by the Duchess of Inverness. The latter necklace appears to have smaller diamonds, although the press remarked on the quality of the diamonds in the Duchess of Inverness' necklace.


It has occurred to me that perhaps another diamond riviere might have been made from the diamonds in the ruby and diamond necklace given to Queen Maud by Queen Victoria. There doesn't seem to be any evidence in the public arena that Queen Maud ever wore the ruby and diamond necklace; nor have we seen it in modern times.
