A wonderful stone for people who like to feel needed, but are being taken advantage of! Great for overcoming feelings of vicitimisation.
Snow Quartz is very good for encouraging tact, and helping people to think before they speak - perhaps turning a 'yes' into the occasional 'No'!
For meditation Snow quartz is very good for seeking inner wisdom that has previously eluded you.
On a physical level, Snow Quartz has the same healing properties as Clear Quartz.
