Just as there are different protocols and etiquettes in royal families across the world, from ultra-conservative to more modern takes, each monarchy also has its own individual approach to tiaras.
Some, like Belgium, prefer their headwear to be on the daintier side, opting for petite designs and subtlety oversize. Others, like the Danish, gravitate towards more unique motifs, including steel flowers and ruby leaves.
But in every royal family, there are the big guns.
Below, a look at the biggest (and sparkliest) of them all.
