Well, it was not until last year that I did bump into some geology-geeks and joined this awesome rock-and-stone group. And though I love rocks and stones for their metaphysical properties, it was good to know some matter-of-fact bits I would have had to go back to high school for just to learn. And it was through this group that I winded up in the page of "Awesome Geology". That's where I found out my enthusiasm over sand color is not without naught.
As it turns out, sand takes it color from the rock/mineral content, such that colored sand (pink and even green) contain crushed pieces of precious gems and stones.
