Astrophyllite Crystal/Mineral. So pretty and it shines and looks so much like Christmas tinsel throughout. Fun piece to add to your collection or as a starter piece. I originally wanted to collect one of everything and then I ended up getting way more than one of each piece because everything is always so beautiful and unique in its own way! This is a very pretty piece but I need to downsize so I can move! Small imperfections are to be expected with natural Crystals/Minerals. So if you see what looks like damage or a chip in the stone, just beware that sometimes they get them out of the ground with a chip out of the Crystal, polishing does not equal perfection, they are natural beauties that were formed and each item is unique and imperfect but perfect in its own way!!!
