Beth - I quoted direct from The Queen's Diamonds, as I intimated. That work was published in 2012. However, I recalled the much earlier work stating that the 21 stones were given unset and decided to add that footnote. Those authors were highly reputable in their field.
The later QD was a Royal Collection publication having been researched by them from original sources. So the QD version carries a lot of weight. Though the book was found to contain some errors.
What is the precise necklace story I do not know.
Someone might like to look at The Times of 4 March 1947 for a report of many diamonds being presented to the royal family.
Edited: searching Trove produces better results, I found, and the articles do suggest that the diamonds for Princess Elizbeth were unset, and that she also received many baguettes. Princess Margaret received 17 diamonds.
