This tiara has beautiful and precise art deco styling and craftsmanship.
However, the dangling diamond seems a bit of a waste. Unless the tiara is worn bandeau-style the diamond simply disappears into the hair. Plus setting a diamond against a background of diamonds doesn't do much to enhance it.

The Royal Order of Sartorial Splendor: Tiara Thursday: The Chaumet Emerald Tiara
This is not one of my favorite tiaras but I do like it. That emerald is simply breathtakingly beautiful. Especially that diamond under the emerald. It does kind of remind me of Wonder Woman but I still think the tiara is very unique and interesting.
I am not completely sure how many times she has worn the Empire Tiara. But I have never seen pictures from other events than those you posted. Your first pic is composed of the State Visit from Belgium in 2007, the State Visit from the Netherlands in 2006 and an official portrait from around 2011. The second pic with the light blue dress is from Victoria and Daniel’s wedding in 2010.You're comment made me wonder how many times MT has worn the Luxembourg Empire Tiara. It's been three years since she's worn it, so I am assuming she rarely wears it. I read that she first started wearing the tiara after Josephine-Charlotte's death in 2005. I researched it, and found out she has only worn it four times. Here are the photos:

MT wore the Chaumet diamond and pearl tiara which can be worn as a choker also a lot since she became Grand Duchess.When Grand Duchess Josephine Charlotte was alive , MT wore the Adelaide tiara or the Chaumet tiara (huge emerald) tiaras JC did not wear a lot, preferring hers.
