Welcome to T-net

Maybe give us a clue where it came from, how heavy and hard it is and anything else you can say about its properties? From the way it has fractured in the picture it appears to be predominantly some type of cryptocrystalline quartz.

It is heavier then quartz it has a grey outer shell that when in light has a rainbow effect. I found it in a river within the kinternite fields in Wyoming near Wheatland. The crystal on the inside has a blue hue when under black light. When I first seen it it was a small piece I thought was jade because it looked green. I did a scratch test on tile glass and a ruby and it scratch all of them.

It does not shatter with a hammer like I have done with quartz that’s why I’m confused.

1st - I noticed this was your very first post - so, Welcome Aboard Rocklegand! You didn't list your state (or country) in your profile. So, you might consider jumping over to Sub-Forum: Select Your Area.... for information (i.e., clubs, hunts, finds, legends, maps, etc.) directly related to your state (or country). You might also consider adding your state (or country) to your displayed profile (SETTINGS -> EDIT PROFILE) - members may have more success helping you (your location may help, etc.)...

2nd - You might consider posting your pictures on ROCKS/GEMS for more exposure...

This looks like pretty typical cryptocrystalline quartz shattering to me (from your second picture):



Everything else you say about it would suggest it's a chalcedony nodule. Those can be pretty tough in the sense of impact resistance (versus crystalline quartz which has cleavage planes)… apart from the hardness. You say it scratches a ruby. Are you really, really sure about that? The only minerals that are going to scratch a ruby are other members of the corundum family or diamond. I don't see it as either of those possibilities and certainly not an enormous diamond.
