Sadly, I have never found a photo of Mrs Greville wearing the necklace, either in its first incarnation or the second.

But we know from Hugh Roberts in The Queen's Diamonds that it is definitely a Greville item.

Roberts notes that QEQM wore the three strand section frequently and for exceptional occasions all five rows.

But QEQM seems to have worn the 5 rows for less grand occasions also.

Below on her way to attend a theatre production in 1957. Not a tiara evening, much less a grand state occasion; yet, HM is wearing all five strands of the Greville necklace.



On grander occasions

Rhodesia 1953



Dutch State visit 1950



Now worn by the Duchess of Cornwall
