(01): Most valuable diamond tiara: The Delhi Dubar because it has settings to fit the Cullinan's 3&4 of 94 and 63.6 carats. They are reported to be of flawless composition and of the highest quality and are also reported to be the most expensive jewels in HM's collection. The close contenders would be the Swedish Braganza and the Luxembourg Empire tiara but it is not clear of the quality of stones they may have. Also the Delhi Dubar can also be fitted to accommodate the Cambridge emeralds making it even more expensive or valuable with this setting.


(02): The most valuable coloured stone tiara: This would have to go to the mighty Vlad with its emerald settings or the ruby and diamond tiara HM had made in the 70's. The dismantled tiara made to create the ruby one was reported to come from the Nizam of Hyderabad and was sourced from Cartier so the stones would of have to been of top quality. But the turquoise tiara loaned to PM by QEQM could also be a surprise contender. And the Swedish Diamond and Sapphire tiara is also in there as well.


(03): The most valuable diamond necklace is the most difficult as one does not know stone composition and grading. But my pics or likely ones are as follows:

(01): The massive Greville Diamond necklace bib.

(02): HM's QE2's triple colliers necklace.

(03): The Dutch diamond bandeau.

(04): The Danish massive diamond necklace the one worn by HMQ Margaret at banquets and personally, I think this one has the sway.

(05): Or the Spanish collier diamond necklace.

(04): The most valuable coloured stone necklace would have to go to HM QE2's Ruby Necklace called the crown rubies. But this could be easily challenged by her mother's Greville Emerald necklace or the ruby necklace with the massive Spinal ruby or even the Kent Amethyst necklace.

I wish I had pictures to post along with all the write up. But thanks Andrew U, this is a good item for debate.
