Hawk's Eye
Hawk's Eye is very closely related to Tiger's Eye. In fact, one of it's other names is "Blue Tiger's Eye". Composition-wise, they're almost the same, hawk's eye is just "younger". Over time it will turn golden. They're both metamorphic quartz - partially quartz crystals undergoing metamorphosis. Sometimes they're also magnetic, because they may contain traces of magnetite.
A lot has been written about all these crystals. In fact, if you spend enough time on the internet you'll read that it does everything from A to Z. I found most places with crystal information online are actually shops, so they also happen to have a vested interest in trying to convince people of how wonderful they are to buy them. The profusion of random unsourced information is kind of like newspaper horoscopes, really. I don't trust them. Hard to know what to trust then besides my own feelings, and I'd sure like to find a source which has information from traditions of experience and use, not from hand-me-down catch-em-all blurbs. I guess I'm a skeptic as a kind of natural defense against too much human input where I don't feel I can trust everything. I kind of wish I had a teacher who won't tell me about these things but who can show and guide me, a sensei. Until then I guess I'm learning on the strongest currents of human knowledge, because there is usually some truth in common wisdom, and my own intuition...
All that said, my understanding and feeling of tiger's eye is that it's a stone of focus, whether for focusing on protection or for problem solving. Not that the stone does the focusing, or you focus on the stone to do stuff, I mean more like, if you let it, it helps focus in a kind of calm, un-busy way. Clarity, without emotional clouding. Helping to dispel anxieties.
Hawk's eye is pretty much the same, except... calmer? Kind of like stress-releasing, anxiety calming. Like, a pool, when it gets calmer, it also becomes clearer, and you can see deeper.
I think it'd make a rather good worry stone, or a stone to meditate with and go deep and far.
For me, not too far, though, I don't feel that in-tune with them, though I like them and they're quite okay. I can work with them maybe as part of a stone ensemble, or another being, I'm thinking. Not plants, maybe, more animalish, or a helping energy being. But, I do think different beings have different affinities. I know someone with such a crazy involuntary affinity for amethyst that it's almost comedic.
