The Duchess wore the smaller version of the historic sapphire and diamond parure in 1984 and 1985 at least in public.
Unfortunately the historic Cambridge sapphires and diamond set, consist of the sapphire and diamond cluster tiara, the sapphire and diamond choker, the sapphire and diamond earrings, the sapphire and diamond brooch was also sold and is not in the royal family anymore.
When the founder of the jewel house Moira died in November 2020, it came up to the light, the historic smaller parure fragments are owned by her.
Nothing is known about the cluster tiara.
