About ulexite
Ulexite is a hydrous sodium calcium borate mineral best known for its unusual optical property of fiber-optic-like transmission. Massive, fibrous aggregates can transmit images along their length, earning the nickname 'TV rock.' It is generally white to colorless, with silky luster in fibrous forms. With Mohs hardness about 2.5 and very low toughness, ulexite is extremely soft and delicate, limiting its use as a traditional gemstone.
