The Colors and Varieties of
Garnet
Chemical Composition
According the whether the Y or the X component in the chemical composition of the
species is constant, we can divide the members of the garnet family into two groups.
Pyralspites
aluminium in Y site
Ugrandites
calcium in X site
Garnet Group
Almandine
Pyrope
Garnet
Garnet describes a group of several closely related minerals.
All species of garnets possess similar physical properties and crystalline forms, but differ in chemical composition.
Garnets are most commonly found in the dodecahedral crystal habit, but are also commonly found in the trapezohedron habit.
Because the chemical composition of garnet varies, the atomic bonds in some
species are stronger than others.
As a result, this group of minerals shows a range of hardness on the Mohs scale of approximately 6.5 to 7.5.
Varieties of Pyrop
Spessartine
Rhodolite
Malaia
Andradite
Dermantoid
Topazolite
Melanite
Grossular
varieties of Grossular
Hessonite
Orange to orange-brown, transparent variety of Grossular Garnet.
Hydrogrossular
garnet is the green, pink, grayish-white to bluish variety of
gross.
Tsavorite
is a ruble that, like Meralani mint, is green in color.
Tsavorite
and green gooseberry are commonly thought to be a function of saturation.
