This is a GREAT introductory kit. The astrology & chakra info is superbly handled. Anyone who has experience with the runes or crystals may find some of their correspondences/keywords a bit off. There is a reference to a UK-based company (out of date address) that offers an extension set of 7 stones; but it is no longer offered. The 12 stones are small (about half to three-quarter inch size) but good quality. You may want to laminate the approximately 9" square cardboard wheels to preserve them. A new set "Power Crystals" ISBN: 1840134399 published by Grange Books combines all 4 mini-kits (5.5" wheels)
Everybody & anybody will has been fascinated by crystals should give this kit a try. There is so much to learn from it. Because of the organization the book it allows you to use the crystals the same way as Tarot cards. This kit is unique in including astrology(twelve houses), rune symbols, five elements, chakras, planets, and its own symbols on 3 different boards. Onto which you cast out crystals to heal, divinate, and also get immediate, direct answers. Even though it is packed with such information, it is demonstrated in a way that beginners can interpret. I recommend this kit to beginners, such as myself, who feel a strong connection to these long-lived crystals.
