Information<\/h2>\n

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

Topas (vanligast misstag), kvartser, Fenakit med flera vita\/f\u00e4rgl\u00f6sa stenar. Danburit kan ju ocks\u00e5 ha andra f\u00e4rger och d\u00e5 andra\u00a0t\u00e4nkbara f\u00f6rv\u00e4xlingsobjekt.<\/p>\n

Behandlingar<\/h3>\n

Bestr\u00e5lning (irradiation), v\u00e4rmebehandling (f\u00f6r att bleka matrialet) \u00e4r t\u00e4nkbar.<\/p>\n

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

Mikroskop\/lupp tiitta efter s\u00e5 kallade ”fingerprints” samt tub liknande inneslutningar (kan till och med ge katt\u00f6ge effekt).<\/p>\n

Specifik vikt och brytningsindex med hydrostatisk v\u00e4gning och refraktometer. Dessa tv\u00e5 test hj\u00e4lper att separera fr\u00e5n Topas.<\/p>\n

Polariskop kan skilja ut p\u00e5 kristall form, dock \u00e4r \u00e4ven Topas ortorombisk vilken Danburit l\u00e4ttast\u00a0f\u00f6rv\u00e4xlas med.<\/p>\n

K\u00e4nda fyndplatser<\/h3>\n

Burma, Ryssland, Japan, Madagaskar och USA.<\/p>\n

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

Namnet kommer av d\u00e4r den f\u00f6rst uppt\u00e4cktes i Danbury, Connecticut, USA. Detta \u00e4r en ovanlig \u00e4delsten som f\u00f6rst nyligen r\u00f6nt uppskattning som \u00e4delsten. Har anv\u00e4nts som diamant simultant.<\/p>\n
