Mineral Group & Geological Identity

Garnet is not a single mineral but a group of closely related silicate minerals that share a common crystal structure. Garnets are classified as nesosilicates, meaning they contain isolated silica tetrahedra within their structure.

Common garnet species include almandine, pyrope, spessartine, grossular, and andradite. Rough garnet specimens from China are often iron- or aluminium-rich varieties, valued for their deep red to reddish-brown tones and strong natural crystal habit.

Garnets crystallise in the isometric (cubic) crystal system, producing naturally symmetrical forms such as:

• Dodecahedrons (12 faces)

• Trapezohedrons (24 faces)

• Rounded or partially formed crystals in rough matrix

With a hardness of 6.5–7.5 on the Mohs scale, garnet is a robust mineral, making it suitable for collectors, educational study, and long-term display.

Colour, Texture & Natural Rough Features

This rough garnet specimen may display:

• Deep red, wine, or reddish-brown colouration

• Natural crystal faces with uneven raw texture

• Vitreous to slightly resinous lustre

• Subtle translucency at thinner edges under light

• Natural inclusions and growth patterns

Because the specimen is unpolished and in its natural state, it retains the authentic surface character shaped by geological processes. Rough garnet is especially appreciated for showing the mineral’s original form before any cutting or finishing.

Each piece is unique in shape, surface detail, and colour intensity.

Formation & Chinese Locality Context

China is an important global source of garnet minerals, with deposits occurring in both metamorphic and igneous geological environments. Garnets commonly form during regional metamorphism, where heat and pressure transform existing rocks and allow new minerals to crystallise.

Rough garnets often develop within:

• Schist

• Gneiss

• Metamorphosed sedimentary rocks

They form when aluminium- and iron-rich minerals recrystallise over millions of years. In some cases, garnets are released from their host rock through natural weathering, allowing them to be collected as individual rough crystals.

Chinese garnet specimens are popular among collectors for their strong colour saturation and availability in attractive raw sizes.

Collecting & Traditional Associations

Garnets have been collected since antiquity for their striking colour and durable crystal structure. Rough garnet specimens are especially valued for showing the mineral in its natural, unaltered state, making them excellent for study and display.

In spiritual traditions, garnet is traditionally associated with passion and vitality; these interpretations are cultural rather than scientific. From a mineralogical perspective, the true appeal lies in garnet’s crystal symmetry, geological origin, and natural raw beauty.
