Generators are either raw or unpolished crystal points, usually (in the case of Quartz varieties) with 6 sides, and six faces at the top coming together into a point. They are usually (but not necessarily) flat at the base so that the piece can sit on its base and point upwards. They are called generators because that is quite literally what they do – they generate & project the energy of the gemstone into the space in which it sits, or towards the intention that it has been programmed to. As such, they are very powerful tools. They are popular not only because of this metaphysical function, but also because they are very striking to look at & they stand proud in their space. They are very useful in all situations where powerful crystal energy is required, from altars & shrines, to meditation & healing spaces, and around the home & work-space. They are also very useful in the cleansing of other crystals because as a tool their function is very clear & accessible.
