I don't think this is Crown Princess Margaret's laurel wreath tiara/necklace which has not only more of the diamond leaves (10 + 12) but also a more distinctive size difference between the leaves in the upper and lower tier.
Apart from that the few pictures we know of the Swedish piece worn as a necklace it was worn as a single row of diamond leaves with the centre diamond drop. The design of the necklace in the Boucheron tweet with the clips on the left and right connecting the two tiers of leaves to the single row in the back looks decisively later than 1905.
Christie's sold another Boucheron necklace similar to Crown Princess Margaret's a couple of years ago. This one seems to be just another version of comparable design.
