The following crystals are the remaining 8 from the original 12 purchased from a man whose family who has their own mine in Brazil. He advised that his brother came across these unique crystals growing within the Amethyst cave, and that the colour is natural and has not been affected by heat. Irregardless, of this fact, I find the colour of them quite unique, and felt the strength in their energy and wanted to purchase them. It was quite amazing when I walked into his showroom, I could feel this pull from behind me and when I turned around the crystals were literally jumping up and down, saying, "She is here, she is here". I have not had this happen before and was quite absorbed and I called them my "12 Sentinels", and I knew they would go to special people, and they would know. I have kept 2 for myself and have them with me in my study and for when I do my readings, and have sold another 2 before listing the remainder on my site. I engaged a professional photographer to take their photos so that their many features can be easily seen and felt, and, that you are able to choose the crystal that is choosing you.
