Diploma (level 3)

Once the Certificate level has been completed, students can then continue onto the ACHO accredited Diploma. This is a further 10 days of training which is normally held one day per month. Many suggest that this level is more spiritual as it encourages students to explore their own relationship with the mineral kingdom and the world around them. Higher vibrational crystals and advanced healing tools are explored to further expand your knowledge and skills.

"Every session has been a magical and healing experience. I feel HCCH workshops and courses need to be experienced to be believed. I started off just doing a one-day workshop so see if it felt right for me and am so grateful I did. It's also been nourishing to spend time with like-minded crystal lovers and mentally stimulating to learn in detail about stones and the many ways you can use them. It's furnished me with much more than I ever could have expected."

"The 2 year diploma course was life changing for me. I signed up because I was interested in crystals and I am now practicing crystal Therapy, something I never envisioned. The course was interesting, fun, serious and sometimes emotional and our inspirational tutor Sandra made the learning so absorbing. I was sad it came to an end."

"Amazing!! I have just completed the two year diploma course with Sandra and can honestly say I have loved every moment. Sandra is a gifted teacher who shares her wealth of knowledge in a wonderfully accessible way. I have learned so much and to anyone considering a course in the area, I cannot recommend Sandra and her College highly enough,"
