Ulexite is a crystal that displays fibre optic properties, and is named after German chemist George Ulex. Although most Ulexite is found in masses very similar in appearance to Satin Spar, it can also rarely be found in white, radiating needle clusters.

Ulexite provides valuable support for the processing and understanding of thoughts and emotions. Ulexite acts as a bridge to the spiritual realm, facilitating a deeper connection with one's Spirit guides and enhancing spiritual communication. It serves as a valuable aid in developing clairvoyant abilities, allowing one to tap into their innate intuitive gifts and perceive subtle energies. Ulexite also aids in visualisation and meditation practices, helping to create clear mental images and enhance the depth of meditative experiences.
