It's quartz...maybe. The crystal foramtion is what's throwing me. My sample is banged up, but still the crystals appear to be 5-sided, not 6.
What is saphira? I couldn't find anything onine. I found corundum, fo sapphire, but the mohs scale is too high for my sample, a 9. My sample is closer to a 7. Also corundum streaks colorless and my sample streaks white.
Clinozoisite is a similar mohs, but streaks greyish-white.
