Hi, I hate to ask a question without posting a pic, but hopefully my description from memory can ring a bell with anyone who is helpful enough to read and answer this question.
I will start with location, Tuolumne County near Sonora and Columbia California. About twenty years ago, while roaming through some BLM land, a local who was showing me some old diggings picked up a rock about the size of a soda can near the bottom of a large hard rock tailings pile. He remarked that it was something of importance that I can't remember, because it looked like a gray semi-porous rock, almost like a gray pumice stone, yet heavy. Later he gave it to me, and when I got home, I used a lighted pocket microscope, and noticed inside some of these pores were, small bright gem-like singular crystals, some being bright red, others bright green, now I can't remember if they were cubic or pyramid shape. I do know they were very small, but the colors were solid and perfect shades of ruby red and emerald greens. I want to say there may have been blue ones, but can't confirm, as it was so long ago, and the rock disappeared, when I believe someone, who saw I was finding gold in quartz specimens, with my detector, had likely smashed it looking for gold. Lol. The rock looked like the bluish/gray porous material, that I see on quartz specimens I have found, that have a weak concentration of gold, possibly from near the contact rock, of the vein. So if this sound like a familiar occurrence to someone, I would love to know what it is? Not that I think it had monetary value, just trying to identify something I've never seen before or since. Thanks in advance for anyone who didn't fall asleep reading this, and a big thanks, to those who can solve my little mystery, so I can get some sleep.
