I am not an expert, but I was interested to know this answer myself, a while ago. My research led me to this:
Stones harder than Steel
1. Diamond - the hardest mineral on earth;
2. Corundum* (depending on color: Ruby, Padparadscha, sapphire);
2. Diorite* (not a precious stone, therefore rarely mentioned);
3. Chrysoberyl (depending on color: Alexandrite, Cat's Eye or Cymophane);
4. Granite (not a precious stone, therefore rarely mentioned);
5. Topaz;
6. Quartz;
7. Feldspar;
All the above stones are stronger than steel.
8. Apatite (can be scratched by steel);
9. Fluorite (can be scratched by steel);
10. Calcite (can be scratched by a coin);
The following two can be scratched by fingernail:
11. Gypsum;
12. Talc;
*I'm still trying to find out if Corundum is harder than Diorite, or vice-versa.
