Meghan Markle is the very definition of a modern royal.

And despite recent rumors that the Queen had banned the Duchess of Sussex, 37, from borrowing jewelry from the Royal Collection, monarchy expert Emma Forbes insists there’s a simple explanation for why we have yet to see the new mom in one of those priceless gems.

WHY DID MELANIA TRUMP, QUEEN ELIZABETH, KATE MIDDLETON AND CAMILLA PARKER BOWLES ALL WEAR WHITE TO THE BUCKINGHAM PALACE BANQUET?

“She’s not really, to me, a tiara kind of girl,” Emma Forbes said of Duchess Meghan, “whereas Kate [Middleton] is more traditional."

“She’s not really, to me, a tiara kind of girl,” Forbes explained, “whereas Kate [Middleton] is more traditional. You know, the royal jewels, they’re mind-blowing, but they are quite traditional. You have to be that sort of person.”

But just because Markle prefers classic diamond studs to the heirloom brooches 37-year-old Middleton wears doesn’t mean she’s averse to splashing out for designer duds, as her pricey maternity outfits proved.

“I think she dressed beautifully throughout her pregnancy,” Forbes said. “And I know she got a lot of flak because it was such an expensive wardrobe, but I love that about her. I think she’s very much the new Princess Diana. Kate is the person who wears High Street, and I think she does it brilliantly. Kate in a Zara shirtdress — everybody goes crazy.”
