I had purchased an Amazez Azeztulite from Doorways to Power, and read in the description that Amazez Azeztulite has a special affinity for Guardianite, so I wanted one. I love the one I purchased on Doorways to Power. It's on the altar with my John of God Phantom Quartz (also purchased from Doorways to Power) and Amazez Azeztulite. One side of the Guardianite is polished and has such a nice feel, and a great energy. In the photo, the John of God Phantom Quartz is on the left, Guardianite in the center, and Amazez Azeztulite is on the right. I also purchased a Green Phantom Deva Quartz from Shilona a long time ago, and I included a photo of that (crystal on the right among 2 other quartz crystals). I recommend any of the crystals from Doorways to Power.
