Why Are Demantoid Garnets So Bright?

Firstly, the name… when they were first discovered in the Ural Mountains in Russia, demantoids were named so because they were diamond-bright. Their refractive index is higher than ruby or sapphire. They also have remarkable ‘dispersion’ or ‘fire’ – the ability to split white light into all the colours of the spectrum. In fact their dispersion rating is higher than that of diamonds! And this is all beause of it’s chemical composition – demantoid garnet belongs to the andradite variety of garnet, and is a calcium iron silicate. 

Well enough of that – here’s another image of that beautiful ring…
