So the popular singer Sting wasn’t that wrong — desert roses do exist! On a serious note, these desert roses are formations of crystal clusters of gypsum or baryte, which include a lot of sand grains.

On average, the size of a rose rock is anywhere between 0.5″ (1.3 cm) to 4″ (10 cm) in diameter. The largest one was a cluster of rose rocks, and it was around 39″ (99 cm) tall and weighed more than 1,000 lb (454 kg).
