Almandine Garnet in Matrix – Natural Mineral Specimen from China (45–60mm)

This Almandine Garnet in Matrix specimen from China is a genuine natural mineral example, showcasing deep red garnet crystals embedded within their original host rock. Measuring approximately 45–60mm (full sizing please see photo), this is a carefully chosen piece selected for crystal visibility, colour richness, and overall display appeal. The photograph provided shows an example of the actual specimen you will receive. Each item includes a Certificate of Authenticity lifetime guarantee generic card, confirming it as a genuine mineral specimen.

Mineral Species & Chemical Composition

Almandine is an iron-aluminium silicate belonging to the garnet group, with the chemical formula:

Fe₃Al₂(SiO₄)₃

It is classified as a nesosilicate mineral and crystallises in the isometric (cubic) crystal system. Garnets are well known for forming symmetrical, equidimensional crystals, most commonly:

• Dodecahedrons (12 faces)

• Trapezohedrons (24 faces)

• Subhedral to euhedral crystal forms when embedded in matrix

Almandine has a hardness of 7–7.5 on the Mohs scale, giving it durability and making it suitable for long-term cabinet display. Its vitreous lustre and strong internal structure make it one of the most recognisable garnet species in mineral collections.

Geological Formation & Matrix Context

Almandine garnets from China typically form within metamorphic rock environments, particularly schist and gneiss. These rocks were subjected to intense heat and pressure during regional metamorphism, causing iron- and aluminium-rich minerals to recrystallise into garnet.

When garnets remain partially or fully embedded in matrix, they provide valuable geological context. The surrounding host rock represents the original formation environment and enhances both the scientific and display appeal of the specimen.

The matrix may consist of metamorphic silicate minerals such as mica, quartz, or feldspar, depending on the specific locality. Garnet crystals often grow porphyroblastically within the host rock, meaning they developed during metamorphism and became enclosed within the surrounding mineral fabric.

Colour, Crystal Habit & Visual Characteristics

This Almandine Garnet in Matrix specimen may display:

• Deep red to reddish-brown crystal faces

• Subtle burgundy tones in strong light

• Vitreous lustre on exposed crystal surfaces

• Well-formed dodecahedral or trapezohedral geometry

• Strong contrast between red garnet and lighter host rock

Depending on crystal thickness and lighting, edges may appear translucent, revealing the natural depth of colour. Surface textures and inclusions reflect natural growth conditions and are part of the specimen’s geological authenticity.

Each piece is naturally unique in crystal placement, matrix composition, and overall structure.

Collecting & Traditional Associations

Almandine garnet has been admired for centuries for its natural symmetry and deep red tones. Specimens in matrix are especially valued by collectors because they preserve the geological setting in which the crystal formed.

In spiritual traditions, garnet is traditionally associated with vitality and strength; these interpretations are cultural rather than scientific. From a mineralogical perspective, the primary significance of this specimen lies in its crystal structure, metamorphic origin, and natural growth within matrix.
