A Harmonizer is a word used to identify two identical crystals/stones which can be used interchangeably. Harmonizers are used to improve the way you feel and to raise your vibration or energy levels. By meditating with Harmonizers you can tap into universal energy and light. Harmonizers can come in a plethora of different crystals but their over all shape essentially stays the same. Harmonizers can be made of the same crystal/stone or have two varying crystal/stones that simultaneously work together such as Selenite and Black Tourmaline.
