Blue Fluorite with White Quartz

Description

An unusual and highly decorative Huanggang specimen, combining lustrous cobalt-blue Fluorite aggregates with pale green zoning and strongly contrasting white Quartz.

This substantial cabinet specimen presents numerous deep cobalt-blue to inky blue Fluorite crystals forming rounded, highly lustrous aggregates across a contrasting white Quartz matrix. Their rich colour and reflective surfaces create strong visual impact under direct and ambient lighting.

Smaller vivid blue crystals trace the edges and surfaces of the Quartz, linking the larger Fluorite groups across the full composition. Areas of pale green to blue-green zoning are visible around selected margins, adding depth and tonal variation.

The white Quartz provides both structure and exceptional contrast. Larger sharply formed crystals rise between the Fluorite aggregates, while finer crystalline coverage adds texture throughout the matrix.

Measuring 21.5 cm across and weighing 1.234 kg, the specimen has the scale and three-dimensional form expected of a serious cabinet display piece. It presents attractively from several angles and is supplied with its display stand and certification card.

Provenance: Huanggang Mines, Keshiketeng County, Chifeng, Inner Mongolia, China. Any stated discovery date should be read in conjunction with the supplied certification and provenance information.

Handling and care: Support the specimen from its solid matrix when moving it. Fluorite has perfect cleavage, so avoid impacts and pressure on projecting areas. Keep dry and clean only with a soft dry brush.

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 accompanying Quartz brings a silicate crystal habit into the association. Its surfaces and crystal outlines contrast with the featured mineral, giving the specimen more than one kind of growth to examine. The way the minerals occupy the same piece is part of its character: the setting retains their natural relationship and adds depth to the overall display.

Fluorite is calcium fluoride and crystallises in the cubic system. Cubes and octahedra are among its familiar forms, but intergrowths, modified faces and changes during growth can produce much more complex outlines. This combination of recognisable geometry and considerable variation makes Fluorite a rewarding mineral to collect by both crystal habit and locality.

Fluorite can be colourless or show a wide range of colours, sometimes within one specimen. Transparency, crystal thickness and illumination influence how those colours appear. Its glassy faces contrast with more textured areas and any accompanying matrix. Colour zoning and fluorescence are separate properties; a particular response under ultraviolet light should only be expected where it has been recorded for the individual piece.

The recorded origin is Huanggang Mines, Inner Mongolia, China. Within a collection of Fluorite specimens, this locality gives the piece a geographical identity alongside its particular crystal habit and natural setting.

The specimen measures 21.5 × 13.5 × 5 cm, with a recorded weight of 1.234 kg. Its scale gives the natural architecture room to be appreciated as a whole, while the finer growth provides detail for closer study.

Condition: Natural contacts, cleavages, matrix edges and extraction-related irregularities may be present. Please examine all four photographs carefully; the exact natural specimen shown will be supplied.

Fluorite has well-developed cleavage and should be supported by its stable matrix or mount. Avoid pressing on projecting cubes or corners. A secure indoor position allows the natural geometry and colour to be appreciated while keeping the exposed growth protected.
