Have you lost track of all the celebrity engagements this year? Let me refresh your memory. Couples include Jennifer Lopez and Alex Rodriguez, Sarah Hyland and Wells Adams, Katy Perry and Orlando Bloom, and many more. While all of these engagement rings were nothing short of stunning, I have to say that none of them were particularly up my alley—but then came Cressida Bonas. 

You might remember Bonas as one of Prince Harry's famous ex-girlfriends, but now she's engaged to Harry Wentworth-Stanley. In August, she debuted her ring: a beautiful art deco style known as a target ring. Bonas's includes a gold center encircled by rubies, with another outer layer of gold. Target rings might be my favorite engagement ring trend of the year, and if you agree, you'll be pleased to find some beautiful options below.
