2The Duchess of Angoulême / Queen Hortense jewels (emeralds & historic stones) — impossible to replace

The Apollon display includes multiple named pieces: tiaras and gem sets linked to figures such as the Duchess of Angoulême, Queen Hortense and others. Even when a precise object hasn’t been named in early reports, journalists and experts point to these figures as the likely provenance of the stolen items.

Historic emeralds, pink diamonds (like the famed Hortensia) or specially cut stones are both rare and extremely difficult to re-create without losing the object’s identity. Their cultural price thus blows far past any private price tag — and that’s what makes them among the top five losses.
