why did my pink rose quartz turn clear when i was holding it and fell asleep with it in my hsnds when it was p?
I kept a chunk of amethyst and three bits of different colour quartz in my tank and it was fine. But to be in the safe side, I put them in a bowl and poured boiling water over them first. Did it twice. I found it looked nice, and easy to clean if algae appears.
