Garnet

<p>Garnets ( /ˈɡɑːrnɪt/) are a group of <a href="/facts/Silicate_mineral/WclrQW2I">silicate minerals</a> that have been used since the <a href="/facts/Bronze_Age/c09qWcTt">Bronze Age</a> as <a href="/facts/Gemstone/kHffmvE3">gemstones</a> and <a href="/facts/Abrasive/UJ9TvVMx">abrasives</a>.
</p><p>Garnet minerals, while sharing similar physical and crystallographic properties, exhibit a wide range of chemical compositions, defining distinct species. These species fall into two primary solid solution series: the pyralspite series (<a href="/facts/Pyrope/A0fdIhrs">pyrope</a>, <a href="/facts/Almandine/4VxjwYv2">almandine</a>, <a href="/facts/Spessartine/SJw17N0W">spessartine</a>), with the general formula [Mg,Fe,Mn]3Al2(SiO4)3; and the ugrandite series (<a href="/facts/Uvarovite/nBnGC15w">uvarovite</a>, <a href="/facts/Grossular/Jq4Mmlbb">grossular</a>, <a href="/facts/Andradite/pqYo9sBw">andradite</a>), with the general formula Ca3[Cr,Al,Fe]2(SiO4)3. Notable varieties of grossular include hessonite and <a href="/facts/Tsavorite/IxWJMhXK">tsavorite</a>.
