In September of last year, a revolutionary air purifier was revealed to the public in Rotterdam.

Dubbed the 'Smog Free Tower,' the 23-foot pollution-eating machine not only sucks in smog, it turns the particles into gemstones, as well.

The revolutionary air purifier is a result of three years of hard work by Dutch designer Daan Roosegaarde. 

Gizmodo reported in September that the tower scrubs the pollution from more than 30,000 cubic meters of air per hour. Then, it condenses the smog into tiny "gemstones" that can be embedded in rings, necklaces, cufflinks, and much more.

Each gem stone is roughly the equivalent to cleaning 1,000 cubic meters of air.
