I bought this item as a Christmas gift for someone who absolutely loved it. She told me that the necklace is so well made and beautiful that she gets compliments all the time about it people asking her where she got it from. Because of this item, she now wants to know all she can about Obsidian because she said feels a powerful force around her that gives her peace. I told her about the ebook that came with it which covered a lot of information about Obsidian and she begged me to print it for her which I did and she just can't stop thanking me. This gift of this item has now prompted her to learn more about crystals. She said she wears it all the time and feels such a powerful energy coming from it which is why she wears it all the time.
