What is this crystal?

May possibly be milky quartz, is it valuable?

I don't believe so, I used to find quartz everywhere when i was little digging around my back yard. It's a pretty common crystal I think.

Edit: Upon a quick google search quartz is very common. Easily obtainable at a lot of different places and has a varying worth depending on size and type. Tho that worth is never really very high so don't get your hopes up. :P

My sister would probably buy it from you for its "mystical healing properties".

[muto]

was gonna say some kind of quartz.

Maybe theres an online chart for minerals to compare.

Quartz is pretty common, but big chunks are harder to find it seems. Keep it if you like it! I thought I was cool cuz I found a big 4 inch diameter pyrite (fool's gold), not a single bit of rock attached to it, just the pyrite. It was so shiny! I still have it even though I know it's not worth anything.
