Garnet is a prominent and well-known gemstone which owns many chemical and physical properties like colour, specific chemical composition, streak, diaphaneity, luster etc. which are listed below:

How Garnet gets its colour?

Garnets are found in almost every colour. Transition metals like iron, manganese, vanadium and chromium enable the garnets to develop different colours.
Most of the garnets are red in colour but they also occur in white, pink, yellow, orange, green, brown, purple and black colours. Blue garnets are rarely found.
In pyrope garnets, chromium or vanadium handles the development of red, pink, purple, blue and green colours. (Orange and yellow colours of spessartine are primarily due to manganese. Purplish red colour in almandine garnets is due to the presence of iron. Fe2+, Fe3+ charge transfer processes cause brown, red and yellow colours in andradite garnets.

Different types of garnets with their colour schemes are given below:

Almandine Fe3Al2(SiO4)3 Deep red to brownish red to purplish red
Pyrope Mg3Al2(SiO4)3 Deep red to nearly black
Spessartine Mn3Al2(SiO4)3 Yellow, orange, pink, red, brown
Grossularite Ca3Al2(SiO4)3 White, yellow, green, pale red, pink, purple, brown, grey
Andradite Ca3Fe2(SiO4)3 Yellow, orange, pink, red, brown, green, black
Uvarovite Ca3Cr2(SiO4)3 Emerald-green
Hydrogrossular Ca3 Al2 (SiO4)3 White, pink, green, to bluish green, brown, grey
