For example, the 352 carat Timur Ruby, a giant gem with a history from the 1300’s AD which is now part of the British crown jewels, was thought to be a ruby. Then, in 1851 it became clear that the gem was actually a red spinel. Another ruby-imposter in the British crown jewels is the 170 carat Black Prince’s Ruby, a huge bead-shaped red spinel that is set as a centerpiece in the Imperial State Crown.
