Also known as 'Agnitite' or Carnelian Quartz. As the name suggests this is a variety of clear quartz from Madagascar that has hematite (iron) inclusions within, some of which are evenly distributed through the quartz and some of which are denser and laid down within fissures or fractures that were created when the quartz formed.
This mineral is ideal for use when you wish to ground an experience, or add the element of grounding to work that you are doing, without dropping the resonance too much. This too is a useful crystal to use at any chakra or centre, but has an affinity with the lower 3 chakras and the Omega centre in particular. It may also be of some use on the 3rd eye or Soma centre when journeying, when it may act to help ground or bring back information or knowledge.
