Agreed. As a necklace it's quite lovely. As a tiara it's quite puny.
I thought for sure she'd receive a new tiara with the birth of Izzy. Hmmm

Who knows? There hasn't been a tiara event ever since...
However I wouldn't bet any M&M on it. And if the necklace she received is any indication, she would have to shave her head bald for anybody to notice it....
