Ooo this is fun bc your intuition comes into play;~)
If you’ve got a metaphysical shop in your area, I’d recommend a field trip <3 Stop by, check it out, browse around, even if you aren’t planning on purchasing anything. Pick up anything that catches your eye! Doesn’t matter what color or shape or size~ if it stands out to you, there’s likely a reason ;3; Use it as a museum of sorts to ogle all the pretties & see which stones you’re most intrinsically drawn to ^_^
Once you’ve got a few faves, google is your friend. Or this website here.
HealingCrystals.com is another good one~ great resources & prices! Best of luck on your journey, I’ll be here if you have any other questions >3< Much love!
