1st - I noticed this was your very first post - so, Welcome Aboard! You didn't list your state (or country) in your profile. So, you might consider jumping over to Sub-Forums: Select Your Area.... and selecting location information (i.e., clubs, hunts, finds, legends, maps, etc.) directly related to your state (or country).
2nd - I moved from Today's Finds! over to Forum: Rocks/Gems for more exposure.
Use the larger transparent crystal to scratch the semitransparent green one next to it, it might be fluorite. It should scratch it easily if it's fluorite.
The green-brownish rock looks like slag but it might be copper ore. Your picture is of to low resolution to say for sure.
There is no shape to it, so I can not say anything for sure. All I can see from the picture is that it is a transparent mass. Try scratching it with a steel knife. If the knife does not scratch the crystal it is most likely quartz, and I say that because it is the most common mineral it is not a given.
It won't scratch with a knife and has perfect cleavage all over. Smooth flat surface but the big mass that's hard to see thru along with the entire piece is covered in sharp triangles like mountain peaks angled.

I have another extraordinary bolder looks like a quartz that was ripped somehow in the center twisting it so much it's top is now on bottom. It's the size of my fist weighing at least 5 lbs.
