The video doesn't mention or show the jewels Queen Mary gave to three of her four daughters-in-law upon their marriages to her son (Bessiewallis Warfield Spencer Simpson was not given anything, for obvious reasons, but I doubt she minded as her husband helped her amass a fabulous collection). for instance, Mary created parures for Elizabeth, Marina, and Alice, each with a different type of jewel. Elizabeth got a diamond parure, including tiara, necklace, bracelets, etc, while Marina got the Cambridge Sapphire Parure and Alice got Queen Mary's turquoise parure. All three women were also given additional tiaras and jewels by Mary on their respective weddings, and they were all left even more jewelry in her Will. The Kent and Gloucester jewelry will cease to be "Royal" and then we may see items with a Royal provenence show up at Sotheby's at some point.
