We’re a mere two days away from Halloween, and this year, we’re in for a treat. On Hallows Eve, we will get to experience a “blue moon.” It won’t actually be blue, but it will be the second full moon of the month, which only falls on Halloween once every 19 or 38 years. It will also be the first time in a whole 76 years that there will be a full Halloween moon in every U.S. time zone.

In honor of this momentous moment, here is a round up on some of the best healing crystals to have on hand before then, if you’d like to be able to cleanse or charge them under the powerful Halloween blue moon.
