'''Andradit''' är kalciun-järngranat och finns liksom övriga [[granater]] i rundade kubisk former. Det kan vara som dodekaedrar eller som korniga massor eller invuxna klumpar. Färgen varierar kraftigt från svart (”[[melanit]]”) via gulgrön (”[[topazolit]]”) till rödbrun.<br />
<br />
Den ädla varianten ”[[demantoid]]” kan vara skarpt grön på grund av små mängder [[krom]]. Vanligast är färgerna gult, brunt och rödbrunt.<br />
<br />
== Förekomst ==<br />
Andradit är vanligt mineral i skarn bildade genom metamorfos i kontakt med kalksten eller kalcitiska, magmatiska bergarter. I synnerhet förekommer denna granat i [[järn]]rika [[skarn]], t ex i anslutning till de mellansvenska skarnjärnmalmerna.<br />
<br />
Fyndigheter är också kända på många ställen som [[Italien]], [[Uralbergen]], [[Arizona]] och [[Kalifornien]] i [[USA]] samt i [[Ukraina]].<br />
<br />
Den beskrevs första gången år 1868 i [[Drammen]] i [[Norge]] och namngavs efter den brasilianska mineralogen [[José Bonifacio de Andrade e Silva]], född 1763, död 1838.<br />
