Guys, there isn't an official press release that Catherine is wearing the Saudi Arabian Sapphire and Diamond Suite. The royals don't release statements on the jewels that's been passed down to another member of the royal family.
You can clearly see that Catherine is wearing the Saudi diamond and sapphire earrings:

I know Diana didn't create anything new. What I'm saying is that Diana took apart the diamond and sapphire watch and ring and made up a new set of earrings. Catherine now wear the ones that had at least 10 or 11 diamond surrounding the sapphire.
The palace didn't release an official statement that a couple The Queen Mother's tiara's and necklaces was passed down to Camilla. It's just when you see Camilla wearing the jewels, you know they have been given to Camilla.
I just thought everyone knew that Catherine wear the Saudi Diamond & Sapphire Earrings frequently.
