According to tradition, a royal bride wears a tiara on her wedding day. Queen Elizabeth II wore a tiara for her wedding to the Duke of Edinburgh, as did Princess Diana, who wore the famous diamond Spencer tiara, a family heirloom piece. What tiara will princess-to-be Kate Middleton wear if she so chooses to for her April 29th nuptials to Prince William? A likely conclusion would be that the Queen will lend her a tiara from the Crown Jewels of the United Kingdom collection. However, in anticipation of this momentous royal accessory, InStyle tapped the creative minds of some of our favorite jewelry designers to see what they would design for Middleton’s special day. See tiara sketches for Middleton from Chopard, Van Cleef & Arpels, Swarovski, Royal Asscher, and more in the gallery.
