Quartz with Likely Sphalerite & Pyrite/Chalcopyrite - 70mm Mineral Specimen

This striking one-of-a-kind mineral specimen combines clear to milky Quartz crystal growth with darker metallic mineral areas and flashes of warm brass-gold colour. Measuring approximately 70mm at its widest point, it has a beautifully varied natural surface, with clusters of slender Quartz points rising across the specimen and contrasting against deeper grey-brown and metallic areas beneath.

The most confidently identifiable mineral present is Quartz. The specimen shows numerous transparent to translucent prismatic crystals, some appearing almost clear and others more milky or cloudy depending on their thickness and the angle of the light. Many of the points are closely intergrown, forming a sparkling, textured crystal surface rather than one single isolated crystal.

The darker metallic and brassy sections are most consistent with a mixed sulphide mineral association. Based on their colour, lustre and appearance, these areas may include Sphalerite together with Pyrite and/or Chalcopyrite. Some sections are dark grey to brown with a strong reflective lustre, while others show brighter brass-gold metallic flashes. Because the specimen has no original locality label or laboratory identification, the secondary minerals are described cautiously rather than presented as scientifically confirmed. The photographs show the exact piece offered for sale and should be used as the best guide to its appearance.

From one side, the specimen appears dominated by a dense bed of Quartz points. Turn it over and the character changes completely, revealing more of the darker matrix and metallic mineralisation below. Small glittering gold-toned areas appear between the Quartz crystals, creating a lovely contrast between glassy translucence and metallic shine. The irregular natural form gives the specimen plenty of visual interest from different viewing angles, making it especially suited to a mineral shelf or collector display where it can be turned and appreciated from more than one side.

As with all natural mineral specimens, this piece may show natural fractures, incomplete crystal terminations, small chips, contact marks, matrix dust, rough edges and areas where crystals have grown into or against one another. These characteristics are part of the specimen’s geological formation and extraction history and are not manufacturing faults. The Quartz points in particular should be treated as delicate, as projecting crystal growth can chip if knocked against harder objects.

Quartz is one of the most widely collected minerals and is valued for its clarity, crystal form and enormous variety of natural associations. In crystal traditions, Clear Quartz is often symbolically linked with clarity, focus and amplification of intention. Sphalerite is sometimes traditionally associated with grounding, confidence and practical awareness, while Pyrite and Chalcopyrite are commonly linked in crystal traditions with vitality, motivation, abundance symbolism and personal drive. These associations belong to spiritual and crystal traditions rather than established scientific or medical evidence, and the specimen is not intended to diagnose, treat, prevent or cure any condition or to guarantee any outcome.

This piece would make an attractive choice for someone who enjoys raw crystals, mixed-mineral specimens, geology, metallic minerals or visually contrasting collector pieces. The combination of transparent Quartz and darker, reflective mineral areas gives it a very different feel from a simple Quartz cluster, while its compact size makes it easy to display without taking over an entire shelf.

For care, handle the specimen by its sturdier matrix rather than by the longest projecting Quartz points. Avoid dropping it, placing heavy objects against it or allowing it to knock against other stones. A soft dry brush can be used to remove loose dust from crevices. Avoid harsh chemicals, ultrasonic cleaning, acids or prolonged soaking, particularly because the exact composition of the metallic secondary minerals has not been laboratory confirmed. Store or display it somewhere stable and dry, away from young children or pets.

Approximate size: 70mm at the widest point.
Identification: Quartz with secondary metallic sulphide minerals most consistent with Sphalerite and Pyrite and/or Chalcopyrite; visual identification only and not laboratory tested.
Quantity: One exact specimen only.

You will receive the exact one-of-a-kind specimen shown in the photographs. Natural colour, lustre, crystal growth, markings and imperfections are all part of this individual piece, and once sold it cannot be replaced with an identical item.
