Just so people are aware, these dice are NOT made out of REAL sandstone, no natural sandstone looks like this. The material of these dice is made in a lab and is actually a type of glass filled with glittering powder. I believe the professional term is goldstone. This shouldn't take away from the look of these dice, they are one of the nicer ones I've seen on Massdrop, but it is made from man made material, NOT natural stone.
WashingtonGuyJust because they say it doesn't make it true, and besides, @Ejtastic is right when he says it is nicknamed blue sandstone. Blue sandstone does not mean sandstone that is blue. It would look completely different.
