Photos of Ladies-in-Waiting to Queen Mary wearing grand jewels are scarce. After years of looking, I have come to the conclusion that not allowing (or avoiding) such photos being taken was probably a prerequisite for the position. What ever the scenario, I have no doubt that Queen Mary's ladies all had suitable jewels to wear on grand court occasions.
Lady Bertha Dawkins was one of the Queen's long serving ladies, and many photos exist of her accompanying the Queen on routine royal engagements such as visiting institutions and community engagements.
But, so far I have found only two images of Lady Bertha wearing evening jewels.
The diamond choker seen in the photo below reminded me of a 1906 Cartier creation now regularly exhibited at Cartier exhibitions around the world, but of course the two jewels are not the same.

In the 1933 image below, Lady Bertha appears to be wearing a seed pearl choker with fine diamond spacer bars and a largish pendant -- but the quality of the photo is so poor that I admit I am guessing!
Has anyone else ever seen more photos of Lady Bertha wearing evening jewels?
