It leaves a very blue streak on concrete. Anybody have any ideas? Thanks, Scott

Agree that it may be Lapis Lazuli. Lapis has a blue streak from what I've read.

To me it's looks more like dumortierite in quartz but I guess the pyrite makes it more likely lapis but then dumortierite is called "desert lapis" so the two would look a lot alike in pictures. Lapis is about mohs 5.5 though and dumortierite is closer to 6.5-7. Never seen pyrite in any of my desert lapis specimens..Mel
