Silicon, which is in group IV , why cannot form a giant molecular structure itself like carbon, but with oxygen to form quartz?
It either wasn't real rose quartz or like the other person suggested it just looks different in different light. It wouldn't lose its color if it were real. It would be easy for some gem dealer to have dyed some regular quartz. There are a lot of them that sell by the side of the road. My brother and I found some spectacular rose quartz in the Black Hills of SD. We even found some close to gem quality stones. It is pretty common there but not the gem quality..
Clear is a natural color of quartz. Quartz can also come in several other colors. The pink color can be so light-colored that it can appear white under some lights. And some an be dyed. It's probably that the pink was a very light shade and now just appears white.
