I purchased this product for myself. Having serious chronic arthritis, I felt my Chakras needed to be aligned. The 18 pieces are beautiful. The engraved stones and tumbled stones are the best I have seen (in a beginners kit). As I opened each piece I was amazed at the great value which included a bracelet, necklace, and pendant. The pyramid energy generator would cost more than the whole box in my area.
