The Duchess of Angoulême's Emerald Tiara!your ruby vote: the Duchess of Angoulême's Emerald Tiara wins, its provenance, design, and history surpassing the fact that we don't actually know what it looks like in use.
Your runners up:
2. Queen Victoria's Emerald and Diamond Tiara, my own personal favorite, and the one that gave our winner the biggest competition.
3. Empress Joséphine's Emerald Tiara. Despite the fact that many of you don't like the top stone, this one did quite well for itself.
4. The Grand Duchess Vladimir Tiara, with emeralds, which has been a favorite in the past - but not so much, this time around.
5. The Harcourt Tiara, lesser-known, but with an intriguing design and shape.
Stay tuned for our next poll!
