If you already know what the third eye chakra is and you need a concise article that simply lists the crystals and their properties that will help balance your third eye, this the article for you. My source of reference is The Encyclopedia of Crystals by Judy Hall (2013).
Disclaimer: Though I advocate for crystal healing, I advocate for the advancements in medical science and psychiatric help. Do what you can to heal yourself, but know that these crystals are not a replacement for medicine or psychiatric advice.
