Author of "Twelve Jewels"  turns his attention to the different structure of crystals. Acknowledging his debt to the innovative thinking of Michael Gienger and Walter van Holst, he explores the different forms crystals take - suggesting that their unique inner crystalline composition reflects patterns of behaviour etched deeply into the human psyche. For example, the cubic structure of Calc Fluor, is associated with being fixed and reliable.
Beautiful colour photographs illustrate the many different forms mineral structures take.
The author links these, inspirationally, to different psychological make-ups and common homeopathic remedies such as Sulphur, Zincum Met, and Arsen Alb.
An exploration of  the inner struggles within each crystal family is clearly tabulated, showing their positive axes of healing, along with key themes and word associations.
8 different crystalline structures give rise to 8 different psychological types.
Through his meticulous examination Tumminello shows a world of difference  between the ambitious, controlling, sometimes weasely, Trigonal type - and the manipulated, oversensitive, too open Orthorhombic type.
Many illustrative cases from the author's own practice add weight and depth to this work, which, whilst detailed, is also extremely clear - both in language and text.
A wonderful desktop guide to crystals, homeopathic remedies and psychological types - likely to appeal to homeopaths, psychologists and other health and complementary practitioners.
