I think Queen Máxima will slowly bring "new" pieces:
- the collier from the so-called "New Crown Parure"
- the diamond sévigné in full setting (from the same "New Crown Parure")
- the Borneo bracelet in re-assembled setting
- the art deco devant-de-corsage with the large diamond pendants
- the ancient "Stuart Diamond" as a pendant
- the collier from the Grand Sapphire Parure in orignal setting
- the two massive bracelets from the Grand Sapphire Parure
- the collier from the Peacock Ruby Parure (mirroring the diadem)
- the large devant-de-corsage from the Mellerio Ruby Parure
- the diadem from the so-called "New Crown Parure"
- the triangular motif diamond collier in original setting
- the diamond laurel wreath diadem
- the diamond ears-of-wheat diadem
- the top part from the Van Kempen diadem (with the large diamond stars and upright natural Pearls)
- the remnants from the diamond-and-sapphire collier which was part of the Wedding Gift 1901
- Etc.
- Etc.
Queen Máxima has so many long-not-seen items in the Orange-Nassau collecton to wow us... It is beyond belief.
My predicton for the State Banquet:
HM Queen Margrethe
- the Orange-Nassau pearl poiré diadem
- the diamond collier with the pearl buttons
- the diamond stomacher with the large hanging natural pearls
HM Queen Máxima
- the Bandeau with the old large rose-cut diamonds
- the mirroring rivière (like she wore in Sweden for Victoria's wedding)
- a small diamond broche to fasten her sash
- Queen Emma's art-deco devant-de-corsage with the hanging diamond pendants*
- Queen Juliana's diamond horloge-bracelet
- Two bands from the Borneo diamonds bracelet
* This corsage-de-devant is awesomely impressive, Queen Máxima wore the central stone as a pendant to a diamond rivière, it is really a big bonker,
