Princess Diana's most famous tiara might be one of the most recognizable pieces of royal jewelry in the world.
Despite this close link with the late princess, the glittering heirloom is set to be firmly out of reach to both Kate and Meghan, and the reason why might just surprise you.

Eventhough Diana was seen wearing the valuable piece while marrying her then husband Prince Charles, the piece actually never belonged to her or the Royal family.

Instead, this is said to be a private possession of the Spencers, and that means it will remain with them forever. The diamond-encrusted headpiece was paired with her iconic silk taffeta gown and 25-foot train, and many couldn't help but wonder why neither Kate nor Meghan owns it. Now, it makes sense, as per insiders, as to why they might never get their hands on it.
