I wasn't exactly bored out of my mind when we weren't doing work around the house while I was away. Local surroundings had several areas I could freely scout for any possible new additions to my mineral/rock/crystal collection, and this big-ass batch is what I got while I was there. The huge quartz chunk was something I found at the nearby construction site, people who worked there found no use from it so they allowed me to take it. All of the other smaller pebbles seem to be various types of quartz, chalcedony and even some jasper, if I am not mistaken.
