I noticed this was your very first post - so, Welcome Aboard isomar! 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.)...
Hard to say but interesting. From the two still shots on the bottom the rind shows what appears to be iron staining and the golden bits appear to be pyrites. All that is mixed into what looks like quartz. In the second video I'm kinda scratching my head as the freshly broken stuff flashes with what looks like a schiller effect. The breaks are pretty smooth so it may just be flash. Maybe one can compair it to this video fuss put up not long ago : http://www.treasurenet.com/forums/rocks-gems/615733-wisconsin-moonstone-short-video-schiller.html
