Information<\/h2>\n

Kan f\u00f6rv\u00e4xlas med<\/h3>\n

L\u00e4mpliga instrument f\u00f6r ID<\/h3>\n

Andalusit ger tydligt utslag i dikroskop. Att \u00e4ven turmalin g\u00f6r det som ibland f\u00f6rv\u00e4xlas med andalusit b\u00f6r beaktas.<\/p>\n

Pleokorism hos andalusit ger v\u00e4ldigt specifikt utseende med gr\u00f6nt i mitten och r\u00f6d\/brunt mot \u00e4ndarna f\u00f6rutsatt att detta tagits i beaktande vid slipning.\u00a0Unders\u00f6k med mikroskop, belysning och olika ljusk\u00e4llor f\u00f6r att observera detta.<\/p>\n

Konstatera brytningsindex och dubbelbrytning med refraktometer \u00e4r viktiga data.<\/p>\n

Desitet \u00e4r 3.17 (+\/- .04) vilket tydligt skiljer mot exempelvis safir (aluminiumoxid) och s\u00e5ledes ett viktigt data.<\/p>\n

K\u00e4nda fyndplatser<\/h3>\n

Australien, Brasilien, Kanada, Ryssland, Spanien och Sri Lanka.<\/p>\n

Kuriosa\/\u00d6vrigt<\/h3>\n

Andalusit har \u00e4ven en opak mycket uppskattad form kallad korssten som har ett kors i mitten\u00a0beroende p\u00e5\u00a0hur slipat. Har anv\u00e4nts som amulett i religi\u00f6sa sammanhang och \u00e4r en intressant vacker samlarsten.<\/p>\n
