[QUOTE=xenobia;1562793]This is pure speculation from my side, but still...
I think it's entirely possible that the king and queen has given the modern fringe tiara as a wedding gift to Madeleine. It's a tiara that is privately owned by them. It also seems to have been Madeleines favourite tiara, since she has worn it lots of times before the wedding.
Something interesting I found here from the nobel laureate dinner last year when Madeleine wore the modern fringe:
The King's dinner for the Nobel Laureates - Sveriges Kungahus [NS4 version]
"Princess Madeleine wore a dark grey lace gown. This was accompanied with her own tiara. Princess Madeleine also wore the Order of the Seraphim's light blue ribbon, decoration and grand star."
