Absolutely!
Then the danish royal family would have complete sets in all the most important gems:
the emerald parure
the rubi parure
the pearl poire parure
the convertible floral tiara (or the Baden tiara) and several diamond riviéres, earrings and brooches
and the saphire parure, adding the sold saphire tiara...

I am convinced that if the sale of the tiara would have taken place in present days, most likely Queen Mary would have shown interest in add it to the main line's jewelry colection. Since becoming queen consort she has shown a genuine interest and knowledge in the colection.
