It was in 2003 when scientists from Adelaide, Australia unearthed a glow-in-the-dark gem that looks like a hundred or maybe thousands of fireworks trapped in a glass.
The gem which was called Virgin Rainbow is actually an Opal- a transparent gem made from silica.
Its interior refracts light making it looks like a rainbow which exploded inside the stone. It also has the capacity to change in color depending on the light being refracted.
Take a look at the photo below by Little Things:
Opal also comes in an expensive price. The black Opal would cost as much as 15,000 Australian Dollars. However, it’s such a rare kind and difficult to unearth.
