This might actually be the most stand-out royal wedding tiara of them all. Princess Eugenie of York surprised everyone by wearing emeralds on her big day, and what a set of stones they are.
The latest royal bride chose the Greville Emerald Kokoshnik for her wedding at St. George's Chapel, Windsor on Oct 12, 2018. It's been part of the Windsor collection since 1942 when it was left to the family by the wealthy society hostess, Margaret Greville. Her gems were bequeathed to the Queen Mother and, on her death, they came to the Queen.
The tiara was made in 1921 for Mrs Greville who entrusted the job to the jewelers, Boucheron. The diadem, like many others at the time, was designed to look like the traditional Russian headdress, the kokoshnik, and it features hundreds of pave diamonds set in platinum. But it's the emeralds that really make this piece stand out. That central stone is over 90 carats while there are six smaller green gems on either side of the tiara.
That green matched Eugenie's colour scheme to perfection and just to make this whole bridal look even more perfect, her new husband, Jack Brooksbank, gave her the pair of diamond and emerald drop earrings that she also wore at their marriage.
