Recently, I’ve been working on reviving a popular section of this site that has been unfinished since its launch: The Tiarapedia, the original online encyclopedia of tiaras. This section is an attempt to provide a single, central location with all of the provenance, ownership, and wearer information for the tiaras worn by our favorite royals.

Today, I’m excited to share the launch of one of the biggest sections of the Tiarapedia: the tiaras worn by the women of the main line of the British royal family! From Queen Adelaide’s Diamond Fringe to Queen Elizabeth II’s recent additions to the vaults, some of your favorite royal sparklers are here, along with links to images of and extended coverage about each tiara from The Court Jeweller.

The Tiarapedia was one of the most popular features of my very first royal blog, Mad Hattery, which launched ten years ago this May. (Can you believe that???) A decade on, I’ll be working on debuting a new section of the Tiarapedia here on the blog each week.

You can visit the newest section of the Tiarapedia over here, with all the information you need about the tiaras that regularly appear these days at British royal banquets and receptions. Enjoy!
