Charging crystals in the New Moon is really simple. Your black crystals LOVE the new moon vibe so much and this really helps them release any of that stagnant energy they are holding.
Simply place with intention onto the earth and leave them for a few hours or overnight. If you live somewhere that placing and leaving them on the earth isn’t an option then place on your windowsill or on your balcony.
Intention is key. Talk to your crystal. Here’s an example of what to say.
“I am placing you here with the intention for you to recharge in this new moon energy so we can work even better together for the highest good of all. Thank you for all your support.”
