If we have previously correctly identified the Indian pearls from the Treasury of the Punjab from the photos of QEII then I do not believe that the pearls worn in 1935 are the Indian pearls because 1. The pearls are not as large 2. I doubt if in 1935 Queen Mary would have given her daughter-in-law the Indian pearls. 3. The necklace worn by QEQM in 1935 has a double jewelled clasp. While the pearls from the Punjab are said to have 2 rubies in the clasp, if the pearls QEII has been photographed wearing are the ones in question, the necklace does not have a double jewelled clasp. I believe it is possible to see in the photos of QEII that there are 2 rubies, one above the other - not side by side.
