1. This is very hard and the stripe of green goes all the way through it. Pictures are both sides.


2. This one is porous and very light. I have some that float and some that don't but they look just alike.


3. This one is heavy and very sparkly, tiny sparkly and the surface is rough.


4. This one is also heavy and hard like quartz. All these were found in the Mojave desert.
