Garnets are a group of silicate minerals that have been used since the Bronze Age as gemstones and abrasives. All species of garnets possess similar physical properties and crystal forms, but differ in chemical composition. The different species are pyrope, almandine, spessartine, grossular (varieties of which are hessonite or cinnamon-stone and tsavorite), uvarovite and andradite. The garnets make up two solid solution
Garnet is the name used for a large group of rock-forming minerals. These minerals share a common crystal structure and a generalized chemical composition of X 3 Y 2 (SiO 4) 3. In that composition, "X" can be Ca, Mg, Fe 2+ or Mn 2+, and "Y" can be Al, Fe 3+, Mn 3+, V 3+ or Cr 3+.
Demantoid is a rare and famous green garnet, spessartine (also called spessarite) is an orange garnet, and rhodolite is a beautiful purple-red garnet. Garnets can even exhibit the color-change phenomenon similar to the rare gemstone alexandrite. All garnets have essentially the same crystal structure, but they vary in chemical composition.
garnet stone: its history, origin and composition, and its litho therapeutic properties History of Garnet Stone Used for millennia and over the centuries in jewellery, garnet stone once bore the name ‘Red gem’, from the Latin ‘malum granatum’, a grain fruit closely resembling the colour of pomegranate.
Chemical composition Garnets comprise a group of silicates with the general formula A 3 B 2 (SiO 4 ) 3 in which A = Ca,Fe 2+,Mg,Mn 2+ ; B = Al, Cr,Fe 3+,Mn 3+,Si,Ti,V,Zr; and Si may be replaced partly by Al, Ti, and/or Fe 3+ .
Garnet is a very popular gemstone, and is the most well-known dark red gemstone. Red Garnet gemstones (Almandine and Pyrope) are very affordable and faceted into all types of jewerly, including necklaces, rings, bracelets, and earrings.Round cabochons of red Garnet are also popular and used in rings and bracelets. The variety Rhodolite has become a very important jewelry gemstone
