It is definitely not the Stuart. It is the central diamond from the brooch Queen Emma received as a gift from the Dutch people in 1879 for her wedding. The tiara Maxima is wearing is the necklace from the same national gift. Princess Laurentien is wearing a small version of the bow brooch from the Stuart parure. I am pretty sure we will see the Stuart tomorrow. It's an easy mistake to make: moving images don't give enough security and pictures arrive not in real time, while we are all expecting her to wear the Stuart diamond.
