Gemma Petherbridge, is a wealth of knowledge on all things crystals. As a Crystal Therapist, she has been working with them for 14 years. In that time she has refined and simplified how to interpret these semi-precious stones. In her workshops, she likes to add in some science where possible so people can start to understand there is so much more to crystals than they may expect.

In 2017 Gemma launched @ConscienceCrystals, who source crystal specimens from around the world to sell in the UK. At the same time, she designed her meditation style, which she calls 'Crystal Healing Meditation'. This incorporates the placing of crystals with a deep meditation practice. Gemma now hosts these meditation classes all over the UK.
