Pezzottaite

<p>Pezzottaite, marketed under the name raspberyl or raspberry beryl, is a <a href="/facts/Mineral/LkUFbNmv">mineral</a> species first recognized by the <a href="/facts/International_Mineralogical_Association/BzSmsAYQ">International Mineralogical Association</a> in September 2003. Pezzottaite is a <a href="/facts/Caesium/dXKN1S5k">caesium</a> analogue of <a href="/facts/Beryl/Fl7q1Hl9">beryl</a>, a <a href="/facts/Silicate/7NdthSRM">silicate</a> of caesium,  <a href="/facts/Beryllium/dv295voP">beryllium</a>, <a href="/facts/Lithium/7vXX6BWA">lithium</a> and <a href="/facts/Aluminium/7wmR8jYE">aluminium</a>, with the <a href="/facts/Chemical_formula/hghUtthl">chemical formula</a> Cs(Be2Li)Al2Si6O18. Named after <a href="/facts/Italy/tUf0PDYF">Italian</a> <a href="/facts/Geologist/vGc0tBHB">geologist</a> and <a href="/facts/Mineralogy/MeIK9lx9">mineralogist</a> Federico Pezzotta, pezzottaite was first thought to be either <a href="/facts/Red_beryl/Fl7q1Hl9">red beryl</a> or a new variety of beryl ("caesium beryl"); unlike actual beryl, however, pezzottaite contains lithium and <a href="/facts/Crystal/e2R2mk3E">crystallizes</a> in the <a href="/facts/Trigonal/sSSok8wo">trigonal</a> <a href="/facts/Crystal_system/dMQLk1q4">crystal system</a> rather than the <a href="/facts/Hexagonal_crystal_system/sSSok8wo">hexagonal</a> system.
