I keep coming across books and websites that show various stones, crystals and gems and then tell you what their uses or properties are. Does anyone know of a site or book that is the exact opposite. For example, it might say for better sleep use...and then lists the appropriate stones, etc.? Or for anxiety....and lists the stones for that. I can't seem to find anything that works the opposite way, but it would be so much easier! If anyone knows of either book or website, please share with the rest of us! Thank you!
