Quartz with Pyrite · Fengjiashan · 214 g

Description

Clear to translucent Quartz crystals carry fine red Hematite speckling, contrasting with darker mineral growth and scattered brassy-gold metallic faces. The irregular cluster has sparkling surfaces and detail across several viewing angles.

Quartz is the primary mineral and Pyrite the secondary mineral. Chalcopyrite and Sphalerite are recorded as associated minerals in the supplied specimen information. The Quartz has a hexagonal crystal system and vitreous lustre, alongside metallic lustre in the associated minerals.

The dimensions refer to the mineral specimen.

The crossing arrangement described above is an important part of the specimen’s silhouette. It lets the direction of individual crystals be followed through the group, with open spaces making their outlines more apparent. Intersecting crystals alone do not establish a specific twin law; here the description concerns the visible arrangement rather than a laboratory-confirmed crystallographic relationship.

The recorded Pyrite contributes a metallic element to the association. Light reflects from its faces differently to the non-metallic growth around it, allowing small metallic areas to stand out within the specimen. That contrast is a useful part of the display and gives the piece interest for collectors of mixed mineral associations, as well as the principal species.

The recorded Hematite adds iron-mineral detail alongside the principal crystals. Its distribution and contrasting colour help distinguish different parts of the specimen. Here, that association is appreciated as part of the piece’s natural character, alongside the crystal form and matrix. The identification follows the recorded listing rather than being inferred from colour alone.

Quartz is silicon dioxide, a mineral whose familiar pointed crystals develop as material is added to growing faces. It occurs in many geological settings, including mineral veins and granite-related deposits. The variety of crystal lengths, orientations and degrees of transparency makes it an especially rewarding mineral to compare: pieces with the same composition can have very different natural architecture.

The glassy lustre of Quartz comes from light reflecting off its surfaces. Clear areas allow a view into the crystal, while internal fractures, veils and inclusions can scatter that light and create softer white regions. These features are distinct from the outer crystal faces. Studying both the interior and the outline adds another layer of interest beyond the familiar pointed shape.

The recorded origin is Fengjiashan Mine, Daye County, Hubei Province, China. Within a collection of Quartz specimens, this locality gives the piece a geographical identity alongside its particular crystal habit and natural setting.

The specimen measures 40 × 70 × 33 mm, with a recorded weight of 214 g. The proportions give a useful guide to its place in a display, with the individual crystal arrangement and mineral association remaining the principal points of interest.

For display, support the stable base or the supplied mount rather than a projecting crystal. Quartz is relatively hard, but pointed ends and natural contact areas can still be damaged by an impact. Gentle handling helps preserve the arrangement that gives this individual specimen its character.
