Ulexite: The Natural Fiber Optic "TV Stone"
Discover a spectacular optical phenomenon in the world of minerals: Ulexite, widely known as the Television Stone or TV Stone. This rare mineral (a hydrated sodium calcium borate) possesses a unique internal structure that conducts light exactly like a bundle of modern fiber optic cables.
How the TV Stone Effect Works
The name Television Stone is quite literal. When a high-quality specimen of Ulexite is cut perpendicular to its fine, needle-like crystals and smoothly polished, it reveals its magic: Place it on top of printed text or an image, and the motif is projected from the bottom surface to the top of the stone without distortion. It transmits the image just like a screen – a genuine optical marvel of nature!
Buying Ulexite: What Makes TOP GEO Special
At TOP GEO, we focus on exceptionally clear Ulexite specimens that showcase this fiber optic property to its full potential. However, please do not expect laboratory-like perfection; remember, this is a naturally occurring mineral. Since every TV Stone is unique in shape, size, and clarity, we offer a transparent shopping experience:
- What you see is what you get: You will receive exactly the TV Stone shown in the product photo. No surprises, just guaranteed quality for your collection.
- Expertly Polished: Our pieces are cut specifically against the grain and carefully polished to maximize the image transmission.
Origin and Mineralogy
Ulexite typically forms in arid regions during the evaporation of salt or borax lakes. Major deposits are found in the USA (specifically California's Boron Mine) and Turkey.
Important Care Instructions: Ulexite is water-soluble and delicate. Only clean it briefly under lukewarm, running water and avoid prolonged contact with moisture, acids, or harsh chemicals. As a relatively soft mineral (Mohs hardness 2–2.5), it requires gentle handling to avoid scratches.
A fantastic gift for anyone fascinated by optical phenomena, for budding young scientists, and for mineral collectors who want to amaze their guests with a truly captivating "Aha!" moment.
