Personally, I'm not a big fan of getting crystals via the internet. It is best if you select them in person so that you can handle them and get a good feel for them. You might even find that a crystal will pick you rather than you picking it, lol! And if you are in the vicinity of Evanston, IL, one of my most favorite places for rocks, crystals, and kachinas is Dave's Down To Earth Rock Shop!
I even used to go in there just because the place felt so nice to me! Dave is a very special man, and his wife, Sandy, and his parents are really wonderful, too! And this shop is like a magical space. There is even a dinosaur museum in the basement! And there isn't a lot of flash about this place or their website! They're just down-home-good-people! If you are ever in the area, definitely treat yourself to visiting this shop!
