Wearer: Kate Middleton
Since 2011, the owner
Value Estimate: $300,000
Although there isn’t much information available about this gorgeous ruby and diamond necklace that Kate wore back in 2016, it is obvious that it is very costly. For her 2011 wedding, the Duchess supposedly received the necklace, matching earrings, and a bracelet.

We’re not sure who provided it, but the Mouawad suite is probably worth more than $300,000 based on the sheer number of diamonds and exquisite rubies. It is subtle and not as flashy as some other royal items, which wonderfully complements Kate’s grace and charm.
