's smile wasn't the only thing sparkling on her wedding day
The newly ennobled Duchess of Cambridge
walked down the aisle at the Westminster Abbey in her V-neck Alexander McQueen gown
, designed by creative director Sarah Burton
, and it was accessorized with glittering touches fit for a princess.
Middleton's cascading curls were topped off with a 1936 Cartier halo tiara lent to her by Queen Elizabeth. The tiara, which was purchased by King George VI for the Queen Mother, was presented to the Queen on her 18th birthday, the Palace confirms
The newlywed's look was styled by James Pryce and Richard Ward, who tell PEOPLE they're "extremely honored and privileged to be involved with creating Catherine's wedding look."
With her hair swept behind her ears, Middleton wore leaf-shaped diamond earrings by Robinson Pelham, which were made to match her tiara. They also featured a diamond set drop and pavé set diamond suspended in the center.
The earrings were a gift from her parents, Carole and Michael Middleton.
Sister – and maid of honor – Pippa Middleton
wore a similar pair of diamond earrings, also designed by Robinson Pelham.
