This individually documented natural Clear Quartz weighs 6.959 carats and has been fashioned into a distinctive long octagonal custom cut. Its transparent, almost colourless body provides a clean visual field in which the individual facet architecture and natural internal character of the gemstone remain clearly visible.

Measuring approximately 14.9 × 9.5 × 6.7 mm, the stone has an elongated geometric outline with a balanced face-up presentation. Rather than following a conventional brilliant or standard mixed-cut pattern, the custom faceting gives the gemstone an individual optical character and emphasises the interaction between transparency, facet geometry and internal reflections.

The gemstone has a clarity profile comparable to VS, with limited natural internal characteristics visible within the otherwise clean and transparent material. These features contribute to the natural identity of the specimen while having only a limited influence on its overall transparency.

Its almost colourless appearance allows light to travel effectively through the stone and places particular emphasis on the geometry of the custom cutting. Changing viewing angles and illumination can produce different internal reflections across the elongated facets, giving the gemstone a lively and individual presentation.

Clear Quartz belongs to the quartz mineral species and is particularly well suited to custom lapidary work due to its transparency, durability and ability to accept a high-quality polish. Clean natural material allows cutters considerable freedom to develop unconventional facet arrangements that differ from standardized commercial cutting styles.

No indications of heating or other treatment have been recorded for this specimen. It is therefore presented in its naturally documented state.

As a natural gemstone, fine internal inclusions, growth structures or minor surface characteristics may occur. These features developed during the geological formation of the crystal and contribute to the individual identity of the stone.

With its 6.959 ct weight, elongated octagonal outline, clean transparent appearance and distinctive custom facet architecture, this natural Clear Quartz offers an attractive combination of geometric design, optical depth and natural character. It is particularly suited to collectors, bespoke jewellery or designs requiring an individual centre stone rather than a standardized commercial cut.

This is the exact natural gemstone shown in the accompanying product photographs.

Evaluation Notes

This natural Clear Quartz presents an excellent overall quality profile, combining high transparency, a clean VS clarity appearance and a well-resolved long octagonal custom cut. The elongated facet architecture creates strong internal reflections and a refined geometric presentation, while the near-colourless body allows the cutting design to remain clearly visible. Minor natural characteristics have little impact on the overall optical performance, resulting in a highly attractive and well-balanced gemstone.
