◆Black obsidian is used in making this candle and is a beautiful natural stone formed by cooled volcanic lava. One of the most popular uses of black obsidian is to create a shield of protection to ward off and absorb negative or harmful energies. Like the rest of our Reiki line, this candle is also infused with mica. All crystals are first cleansed through burning sage, then recharged with natural rose water before being placed into each candle. This assures that they are free of any negative energy that may be attached to them so that you can use them with your own intentions.
