Re: Unknown Mineral
I'd guess your rock is some type of feldspar. Feldspar and quartz are the minerals that make up most rocks. Two easy ways to tell them apart are the hardness and the fracture except that very probably you don't want to scratch or break your rock. If you join a rock or lapidary club, you will meet a lot of people who have been handling rocks for years and will have a much better chance of identifying them just by look and feel. If you don't mind some damage to your rocks, look online for mineral identification kits. Good Luck!
