Garnet

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, uvarovite and andradite.

Colors It Comes In - orange, brown, yellow, pink, green, blue, and colorless

Fracture Pattern -

Tensile fractures:
In granulite-facies mylonites and gneisses, garnet crystals can have closely spaced, straight tensile fractures that are perpendicular to the foliation and lineation. These fractures are more likely to occur in coarse grains or grains with a large aspect ratio.
Internal crystal plastic deformation
Fractured garnets can exhibit internal crystal plastic deformation, which can be seen in areas of enhanced diffusion.
Sharp irregular pieces:
When garnets fracture under stress, they can form sharp, irregular pieces because they don't show cleavage.
Radial cracks:
In ultrahigh-pressure garnets, radial cracks can form around SiO2 inclusions due to ultrafast decompression.
Macroscopic channelization:
Garnet crystals can show macroscopic channelization.
Oscillatory zoning:
Garnet can have oscillatory zoning, which can be caused by a number of factors, including changes in growth rate, major and accessory mineral breakdown, and dissolution and reprecipitation.

Shape - symmetrical, cube-based crystal shapes, with the most common being the rhombic dodecahedron

Luster - vitreous to resinous

Texture - Foliated; Fine- to medium-grained

Where It Can Be Found -

Garnets are often found in sedimentary rocks or highly weathered material, where only the hardest materials have been left behind.
