This natural Chlorite Phantom Quartz crystal cluster originates from Kharan, Balochistan, Pakistan, a locality recognised by mineral collectors for attractive Quartz specimens with distinctive internal mineral inclusions and complex growth structures.

Weighing approximately 91 carats / 18.20 grams, the specimen measures around 52.6 × 33.8 × 16.9 mm and presents a naturally formed cluster of Quartz crystals containing visible chlorite-related internal features.

The characteristic phantom structures developed during successive stages of Quartz crystal growth. At certain points during formation, fine chlorite-rich material accumulated on earlier crystal surfaces before additional Quartz continued to grow over them. These preserved internal outlines create the characteristic phantom-like layers visible within the crystals.

The contrast between the transparent to translucent Quartz and the darker greenish chlorite inclusions gives the specimen strong internal depth and allows its geological growth history to remain visually apparent.

Individual crystals may display natural growth lines, internal zoning, mineral inclusions, fine fissures and contact features resulting from their formation within the cluster. The specimen remains in its natural state, preserving original crystal faces and geological textures.

The cluster format adds further visual interest because the crystals interact at different orientations, producing changing reflections and revealing different aspects of the phantom structures depending on the viewing angle.

Because natural rough mineral specimens have irregular shapes, the stated dimensions are approximate and depend on the exact measuring points selected. They are provided as a practical indication of the specimen’s overall size.

Unique Piece: Natural individual formation

With its visible chlorite phantom structures, natural Quartz crystal development and documented Kharan, Balochistan provenance, this compact 18.20 g specimen offers both strong mineralogical interest and attractive collector character. The preserved internal growth stages provide a particularly clear visual record of the crystal’s natural geological development.

Evaluation Notes

This natural Chlorite Phantom Quartz cluster presents an **excellent overall collector-quality profile**, combining well-developed Quartz crystal growth with clearly visible greenish chlorite-related phantom structures and a balanced natural cluster formation.

The specimen shows good visual depth, with transparent to translucent Quartz allowing the internal growth zones, inclusions and phantom outlines to remain visible. Natural contact features, fine fissures, minor edge irregularities and variations in transparency are present but remain consistent with an untreated crystal cluster and do not significantly detract from its overall presentation.

The combination of **phantom definition, crystal development, internal contrast, natural structure and documented Kharan provenance** supports an **excellent 90/100 assessment**.

Transparency NotesThe Quartz ranges from **transparent to translucent**, with clarity varying according to the concentration of chlorite-rich inclusions, phantom growth zones and fine internal veils. Clearer areas allow good light transmission, while more heavily included sections appear locally translucent.
Natural CharacteristicsThe Quartz crystals display natural **growth zoning, internal phantom outlines and chlorite-rich inclusions or coatings** that mark earlier stages of crystal development. Fine fissures, subtle internal veils, contact features and variations in transparency may be present throughout the cluster, together with natural crystal-face growth lines and minor edge irregularities. The contrast between the clearer Quartz and the darker **greenish chlorite features** creates strong internal depth and clearly expresses the specimen’s multi-stage geological growth history. These characteristics are natural and contribute significantly to the cluster’s mineralogical and collector interest.
