This natural Rose Quartz rough gemstone weighs 18.755 carats and is presented as facet-quality material with substantial size and good potential for individual cutting. The specimen displays a natural pink body colour with a transparent appearance characteristic of Rose Quartz.

Measuring approximately 19.4 × 18.7 × 13.5 mm, the rough offers considerable volume and useful depth for orientation, preforming and yield planning. Its broad, relatively balanced proportions provide flexibility when selecting the final gemstone outline and allow the cutter to evaluate different shape options before material is removed.

The transparent body gives the material a soft visual character, while the natural pink colour remains the principal aesthetic feature of the rough. Because Rose Quartz commonly contains microscopic inclusions and internal structural features, careful orientation is important to achieve the most favourable balance between colour distribution, translucency, surface brightness and finished weight.

As facet-quality rough, this specimen provides sufficient material for planning a substantial finished gemstone. The available depth and overall dimensions allow the cutter to consider larger faceted or mixed-cut designs, although final yield will depend on the distribution of inclusions, internal fissures and any structural features identified during preforming.

Rose Quartz is the pink variety of quartz. Its colour is associated with microscopic structural and mineral-related features within the material rather than with an applied surface coating or artificial colour layer.

No indications of heating have been observed, and there are no indications of any other treatment. The gemstone is therefore presented with its naturally observed colour and internal characteristics.

As with natural Rose Quartz, cloudy internal zones, fine growth-related features, inclusions, internal fissures and minor surface irregularities may be present. These characteristics contribute to the individual appearance of the specimen and should be considered when determining the optimal cutting orientation.

With its substantial 18.755 ct weight, attractive pink colour and generous cutting volume, this Rose Quartz rough offers good scope for orientation and individual facet design. It is a promising specimen for cutters seeking larger natural Rose Quartz material with enough depth to explore a well-proportioned finished gemstone.

Evaluation Notes

This natural Rose Quartz rough presents a very good gemmological quality profile, with an attractive pink body colour, translucent transparency and substantial usable crystal volume. Internal cloudy zones, fine growth-related features and minor inclusions reduce transparency and limit optical performance compared with cleaner quartz material, while the available depth and broad proportions provide useful scope for orientation and yield planning. Minor fissures or structural irregularities may require consideration during preforming, but the specimen retains good material integrity and facet potential. Overall, the combination of colour, size, usable volume and structural condition supports a strong quality assessment within this material type.

Natural CharacteristicsNatural rough Rose Quartz structure with internal features, fractures and color distribution that should be considered during orientation and preforming. Natural cloudy zones, fine internal growth features and minor inclusions are visible within the translucent Rose Quartz rough. Subtle internal fissures and surface irregularities may also be present as part of the natural material. The specimen retains an even pink body colour and substantial usable volume, supporting its suitability as facet-quality rough.
