Kyanite (disthene) properties

Known in France as Disthene, this stone is also recognized by the International Mineralogical Association under the term kyanite.

Belonging to the group of aluminum silicates, disthene is emblematic of metamorphic rocks.

Naturally colorless, disthene owes its famous blue hue to the presence of chromium. Its color palette extends from blue to violet, green, yellow, pink, white, brown, and gray.

The name "disthene" originates from the Greek "di," meaning "two," and "destenos," meaning "strength," referring to the electrical properties this crystal acquires through friction, which vary depending on the orientation of the stone. This term was introduced by René-Just Haüy in 1801.
As for the term "kyanite," sometimes spelled "cyanite," it was coined by Abraham Gottlob Werner in 1789 and derives from the Greek "kuanos" or "blue."

Disthene is also known by other names such as foliated beryl, cyanite, sappare, blue talc, Munkrudite, and cyanite zeolite.

Two fascinating varieties of this stone are distinguished. Chrome kyanite, a chromiferous variety, emerges from deposits in New Zealand and Russia, displaying captivating shades ranging from deep blue to emerald green, enriched by shimmering reflections. As for rhaeticite, this variety offers an intriguing color palette, ranging from subtle gray to intense black, bestowing upon each piece a mysterious and distinctive aura.

History, legends and beliefs about kyanite (disthene)

It seems that until the 20th century, kyanite was often mistaken for sapphire, making it difficult to separate its own distinctive stories.

On the internet, there are mentions of kyanite being used as a compass since ancient times. Due to its electrical properties, it is said to have been suspended by a hair to guide travelers.

However, given the lack of distinction of this stone throughout history, I remain skeptical about the accuracy of this anecdote. Similarly, I doubt the mention of kyanite as the base material for the sword of the Archangel Michael, due to the absence of reliable sources.
