I was wondering which stone/crystal you all are using for third-eye meditation? I have a small iolite, which I love, but it's just too dang small! Anything larger would cost an arm and a leg though.... (And that's assuming you could find it in the first place) There are so many blue/purple stones out there, but since I have to order online, I'd love some recommendations. Amethyst is out because its my birthstone, and I've had my fill. Anyone?
