I honestly believe that Queen Alexandra could have commissioned both this necklaces from Cartier, for a woman in her position it is more than likely that she could have had more than one collier résille in her collection.
We now know that Queen Alexandra gave detailed instruction upon the division of her jewels, by notes in her inventory. It could be possible that the garland style necklace was dispersed among her other children, and Queen Mary was left the necklace we definitely know was in the Royal Collection.
There were countless jewels owned and worn by Queen Alexandra, with no photographic record of them actual being worn. The only way to be sure, would be to look in her jewellery inventory, or through all her accounts in the Cartier archives to see if there is any mention of the second one. Field mentions that QA had two collier résille; Roberts definitely mentions one, but doesn't discount the possibility of another, which means that it could be possible. More research would have to be done into it.
