From the black stone ‘Trevorite’ with its strength and metalic sheen. NOT included in sets but may be ordered separately here. Uses: Place one drop onto the Feeling Centre (solar plexus) when people are going through problems with over-shadowing authority. Good to disperse a heavy build-up of negative emotions. This essence helps to calm the system so that the person can be more clear-sighted, rather than going with the negatives that they are being bombarded with, especially when these negative thought forces have been around them for a long time. N.B. A very potent Essence because of the strength of the actual gemstone, so should only be used one drop at a time and always by itself.
