I love how clear your vids are of each specimen. I've been looking for a good reference vid or online photos of just raw minerals meteors still in natural form as its found when picked up or mined. I seen plenty of museum pieces but need something up close and detailed of natural pieces to compare to. I have things that I've never seen anywhere else and like I said its hard to compare one picture to what I've got. Videos or slide shows like you do is awesome. I don't want to bring my pieces to a pro until I have a little research into them..I'm a rock hound by nature but never got around to the names except basic igneious...sedimentary...metamorphic...and quartzs, crystal, and basic mineral ECT...diamond ...ruby...ECT. Till recently ...I've got some strange things and I can not say if its shale, gniess...feldspar...because those things I dont know what it is ...very name illitetate and just need some really good reference. And unless you actually view them as if it was in your hand they look similar even to your impact diamonds... I do know what an impact diamond are...And find them most interesting...
