23 royal necklaces that captured our imagination, from historic jewels to affordable high-street favourites

If we've said it once, we've said it a thousand times - no one knows how to capture our attention (and our imagination) quite like the royals.

With the world's best jewellers and designers at their beck and call - and the need to keep commanding such attention - it's no surprise they often pull out all the stops when it comes to their choice of scintillating, spectacular and sparkling necklaces that'll have every neck craning to sneak a peek. 

From historic million-pound diamonds that have belonged to the family for centuries, to Meghan Markle's affordable high-street charms, these are our all-time favourite royal necklaces.
