I also think she owns it (probably a gift from her husband?) as this is the only tiara I've seen her wear since 2010. She wore it also at Pc Guillaume of Luxembourg prewedding
It was discussed here at the time of CP Viktoria's wedding that the top pearls are probably not very valuable as they seem to be only "half pearl", and the diamonds on the tiara are very small. But still I really like the design and how it looks on Pss Claire, it was a real improvement from her other tiara. Before she wore her small diamond wedding tiara, I believe that one was a piece formely property of Quuen Paola.
