http://gemologyproject.com/wiki/index.php?title=Garnet WebMany properties of garnets vary approximately linearly with end-member composition. The properties of any garnet of known composition may, therefore, be estimated from the properties of the pure end members. The refractive indices, specific gravities, and lengths of the unit-cell edge of the common end members are given in Table 1.

Garnet (name) - Wikipedia
Garnets are unique in that they can record the pressures and temperatures of peak metamorphism and are used as geobarometers and geothermometers in the study of geothermobarometry which determines "P-T Paths", Pressure-Temperature Paths. Garnets are used as an index mineral in the delineation of … See more 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 See more Properties Garnet species are found in every colour, with reddish shades most common. Blue garnets are the … See more Also known as rare-earth garnets. The crystallographic structure of garnets has been expanded from the prototype to include chemicals … See more Gemstones Red garnets were the most commonly used gemstones in the Late Antique Roman world, and the See more The word garnet comes from the 14th-century Middle English word gernet, meaning 'dark red'. It is borrowed from Old French grenate from Latin granatus, from granum ('grain, seed'). This is possibly a reference to mela granatum or even pomum granatum (' See more Pyralspite garnets – aluminium in Y site • Almandine: Fe3Al2(SiO4)3 • Pyrope: Mg3Al2(SiO4)3 • Spessartine: Mn3Al2(SiO4)3 See more The mineral garnet is commonly found in metamorphic and to a lesser extent, igneous rocks. Most natural garnets are compositionally zoned and contain inclusions. Its crystal lattice structure is stable at high pressures and temperatures and is thus found in … See more WebAug 1, 2016 · The structural and crystal-chemical properties of the common silicate garnets, both (nearly) end-member and solid-solution compositions, and the relationships among them have been analyzed by X-ray single-crystal diffraction methods (e.g., Novak and Gibbs 1971; Armbruster et al. 1992; Merli et al. 1995) and using various spectroscopies (Geiger ... fawne toler
