====Almandine==== [[File:Almandine.jpeg|thumb|Almandine in metamorphic rock]] Almandine, sometimes incorrectly called almandite, is the modern gem known as [[Carbuncle (gemstone)|carbuncle]] (though originally almost any red gemstone was known by this name).<ref name="lytvynov">{{cite journal |last1=Lytvynov |first1=L. A. |title=On the words used as names for ruby and sapphire |journal=Functional Materials |date=2011 |volume=18 |issue=2 |pages=274β277 |url=http://dspace.nbuv.gov.ua/bitstream/handle/123456789/135445/21-Lytvynov.pdf?sequence=1 |access-date=7 December 2020}}</ref> The term "carbuncle" is derived from the [[Latin]] meaning "live coal" or burning charcoal. The name ''Almandine'' is a corruption of [[Alabanda]], a region in [[Asia Minor]] where these stones were cut in ancient times. Chemically, almandine is an iron-aluminium garnet with the formula Fe<sub>3</sub>Al<sub>2</sub>(SiO<sub>4</sub>)<sub>3</sub>; the deep red transparent stones are often called precious garnet and are used as gemstones (being the most common of the gem garnets).<ref>{{cite journal |last1=Jensen |first1=David E. |title=The Garnet Group |journal=Rocks & Minerals |date=November 1975 |volume=50 |issue=10 |pages=584β587 |doi=10.1080/00357529.1975.11767172|bibcode=1975RoMin..50..584J }}</ref> Almandine occurs in [[metamorphic rock]]s like [[mica]] [[schist]]s, associated with minerals such as [[staurolite]], [[kyanite]], [[andalusite]], and others.{{sfn|Nesse|2000|pp=312,320}} Almandine has nicknames of Oriental garnet,<ref>{{cite book |date=2009 |pages=19β20 |doi=10.1007/978-3-540-72816-0_532|isbn=978-3-540-72795-8 |chapter=Almandine |title=Dictionary of Gems and Gemology }}</ref> almandine ruby, and carbuncle.<ref name="lytvynov"/>
