7. Princess Beatrice
While Princess Eugenie may have followed in the footsteps of her mother when it comes to engagement ring style, her sister Princess Beatrice went a totally different route. 

Beatrice became engaged to Italian property developer Edoardo Mapelli Mozzi in September 2019. He teamed up with jeweler Shaun Leane to design the ring which features a 2.5-carat round brilliant-cut center stone with two smaller round diamonds on either side. It also has a diamond pavé band that extends halfway. 

Beatrice and Edoardo had planned to marry at Chapel Royal at St. James' Palace in May 2020, but it was postponed due to Covid. The couple eventually settled on a private ceremony, which took place in July 2020.
