I have a beautiful clear quartz pendulum with amethyst on the top. I have had it for about 2 years now and I have found it a very useful tool for finding things and answering questions. It is very responsive and I enjoy using it. I only use it when I need guidance or if someone has lost something or has a question. I read the 'how to use a pendulum' section and I learnt some useful information. I haven't asked for protection or prepared myself before use though in future I will so thanks for that. I look forward to learning more. chrissie x
