It’s neither sky nor water. #YouFindARock!

You pick up the perfectly civic blue crystal ans consider your future life choices.

250 million years ago, a shallow sea covered New Mexico, then evaporated to leave behind thick deposits of sylvite and halite. Gamma emissions from potassium (K-40) isotope decay in the sylvite knocks holes in the crystal lattice of the halite.
