Origin of Name & Mythology: Ulexite was named after the German Chemist Georg Ludwig Ulex (1811–1883) who first discovered it.

When polished, Ulexite becomes the well-known "Television Stone" or "TV Stone" sold to collectors. The optical effect exhibited by Television Stone is caused by each of its individual crystal fibers acting as fiber-optic cables, transmitting light from one surface to the other. Since all the fibers are parallel and compacted together, any image at below is transmitted through each crystal fiber to the top surface. For this effect to be seen, specimens are polished with smooth surfaces. Fibrous Ulexite bundles can also be carved into cabochons that display strong chatoyancy. However, due to its low hardness, it is unsuitable for gem use.

Metaphysical Information: Ulexite is said to stimulate the third eye Chakra, while some believed it has an association with clairvoyance, telepathic and channelling abilities. It is also said to help one read the energy of another with clarity and precision. Some say it may facilitate creative endeavours and moments of inspiration.
