Fire Balls feature a real meteor impact tektite along with other assorted gemstones.

Tektites are one of the biggest little mysteries known to science! Tektites are believed to be formed from molten rocks propelled into space by a meteor impact and re-enter the earth's atmosphere at high velocity creating a natural glass with unique characteristics.

About 5 meteor impact events are currently known to have produced tektites. Despite hundreds of known meteorite craters on earth, scientists are still not sure what special circumstances are required to produce tektite-strewn fields. In composition, they are very similar to obsidian, but differ in their extremely low volatile content (substances which vapourize easily). The specimens used in Fire Balls are from the biggest (and most mysterious) tektite event of all, the Australasian impact about 780,000 years ago, which occurred at a still unknown location somewhere in South East Asia. This event could well have been the largest natural disaster since humans began their walk on earth!
