Natural Chevron Amethyst Rough weighing 94.587 ct and measuring approximately 49.0 × 20.0 × 18.5 mm, displaying the characteristic alternating violet and milky-white quartz banding associated with Chevron Amethyst.

The specimen shows medium to deep violet Amethyst zones contrasted by opaque to translucent white quartz layers, creating irregular chevron-like and wave-like patterns across the rough surface. The colour distribution is naturally uneven, with darker purple concentrations alternating with lighter lavender and creamy-white sections.

Its elongated, asymmetrical form remains completely natural and unpolished, preserving original fracture surfaces, irregular growth textures and subtle surface lustre. Several areas show good translucency under direct light, while denser white quartz bands create stronger contrast and visual depth.

The interplay between violet Amethyst and white quartz gives the specimen a distinctive geological character, with every angle revealing a different arrangement of colour zoning and natural texture. Its compact but elongated profile makes it particularly suitable for mineral collections, display pieces, decorative arrangements or crystal-focused interiors.

A distinctive natural Chevron Amethyst rough specimen combining strong colour contrast, visible banding and authentic unpolished mineral character.

Evaluation Notes

This natural Chevron Amethyst rough specimen presents an excellent balance of colour contrast, geological character and visual individuality. The alternating medium to deep violet Amethyst and milky-white quartz zones are clearly expressed, producing strong chevron-like and wave-like patterns that remain visible from several viewing angles.
The colour distribution is particularly attractive, with saturated purple areas contrasting effectively against the lighter quartz bands. Translucent sections allow light to penetrate parts of the specimen, adding depth and making the internal zoning more pronounced.
Its elongated asymmetrical shape complements the natural banding and gives the piece a distinctive decorative presence. The unpolished surfaces, fracture planes, internal veils and natural growth-related irregularities remain clearly visible and enhance rather than detract from its geological character.
The specimen is not completely uniform in colour or transparency, and some areas are more opaque due to the white quartz component, but this is intrinsic to Chevron Amethyst and contributes to the characteristic appearance of the material.
Overall, the combination of strong natural patterning, attractive violet colour, good contrast, substantial 94.587 ct weight and distinctive rough form supports an excellent evaluation.

Natural CharacteristicsDistinct natural colour zoning is visible throughout the specimen, with alternating violet Amethyst and milky-white quartz bands forming irregular chevron-like and wave-like patterns. The rough surface preserves natural fracture planes, uneven growth textures and small contact areas, while several sections show translucent edges and internal light transmission. Fine internal veils, micro-fractures and growth-related inclusions are present within the purple zones, together with denser opaque to semi-translucent white quartz areas. The elongated asymmetrical form and unpolished surfaces remain fully natural, with minor edge irregularities and surface variations consistent with the specimen’s geological formation and extraction history. These features give the piece its characteristic Chevron Amethyst structure and individual mineral appearance.
