It's didficult to tell from the pic, but it looks rather massive from this angle, I don't think its the Iveagh nor the smaller emerald one. I would say she is wearing Pss Marie Louise's indian tiara (one of my favourites) or the turquoise tiara, but we really need a bigger pic. You are right Cynthia, the Duchess of Gloucester has indeed a fabulous collection of jewels at her disposal, and she wears them so beautifully .
--Previous Message-- : I saw that picture earlier and couldn't tell : which tiara she had on. Can you? She has : such an array to choose from. :
