Three Red Stones – Ruby, Spinel and Rubellite
Did you know that some of the most famous rubies from earlier times are in fact spinels? It was not until 1783 that mineralogist Jean Baptiste Louis Rome de Lisle, identified spinel as a different mineral from the form of corundum we call ruby.
After the identification of spinel, various gems were given a second look. It was found, for instance, that the BLACK PRINCE, the famous 14th century Black Prince’s Ruby in the British Imperial Crown is actually a red spinel.
We shall look at ruby and spinel more closely below and over the page, and also take a look at the beautiful rubellite tourmaline and some jewelry featuring each of these three red stones.
