It was just a cool thing to note, but yes, the series is incredibly inconsistent with the hardness scale. The only gems that we have seen crack are Lapis (fair enough, it's about a 5.5), Amethyst (a 7.0 quartz), and Ruby (Doc); who is actually a 9.0. The meteor that hit her would have to be at least harder than that to actually crack her gem at such little force, so she was basically hit by a floating diamond (10.0 on the scale).
