Jasper ??

[shaman15771]

This is a very red rock. Found in the creek. Was originally covered with black. Was thinking jasper or red aventurine.

That's difficult to say. I don't think its jasper, but something else, perhaps related to quartz.

Not a jasper~ a highly mineralized quartzite is my opinion. Alexandrite is the red form of Chrysoberyl. Both would show glass like fracturing and smooth surfaces. Keep chipping.
