The rest of the process happens more or less naturally, as crystals begin to form in the saturated solution. And boy, did they grow — long, prismatic lime-green crystals, with a beautiful ...

Polishing the crystals to make them optically cleaner would be a good next step, as would perhaps growing even larger crystals.

The two giant blobs — one beneath the Pacific ... Crystals in the mantle take a long time to grow, Deuss said, so the larger crystals in the LLSVPs have likely been undisturbed for quite some ...

In nature, giant salt crystals form by cooling in caves ... humidity (the moisture of the surrounding air) has an impact too. Crystals grow more easily in dry environments, where solutions are ...
