Natural Clear Quartz · 11.855 ct · Round Custom Cut

This individually documented natural Clear Quartz weighs 11.855 carats and has been fashioned into a distinctive round custom cut. Its transparent, almost colourless body provides a clean optical field in which the individual facet architecture and natural internal character of the gemstone remain clearly visible.

Measuring approximately 14.9 × 14.8 × 11.1 mm, the gemstone has substantial depth and a strong face-up presence. Rather than following a conventional brilliant or standard mixed-cut pattern, the custom faceting has been designed to create pronounced internal reflections and a highly individual visual presentation.

A particularly distinctive feature of this specimen is the eye-like effect visible from the surface. This appearance is created by the interaction of the custom facet geometry, depth and internal reflections within the transparent Quartz. As the viewing angle and illumination change, the central reflections can produce a structured, eye-like visual impression across the face of the gemstone.

This effect should not be confused with an intrinsic optical phenomenon such as chatoyancy. It results specifically from the custom cutting design and light behaviour within the stone.

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

Its almost colourless appearance allows light to travel effectively through the gemstone and places particular emphasis on the geometry of the custom faceting. Reflections from the surrounding environment may also become visible within the stone because of its high transparency and near-colourless body.

Clear Quartz belongs to the quartz mineral species and is particularly suitable for precision and experimental lapidary work. Clean material of this size allows cutters considerable freedom to create unconventional facet arrangements and optical patterns that differ substantially from standardized commercial cuts.

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, subtle 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 substantial 11.855 ct weight, clean transparent appearance and distinctive eye-like facet pattern, this natural Clear Quartz offers an unusual combination of geometric cutting, optical depth and individual character. It is particularly suitable for collectors, bespoke jewellery or designs where the custom facet architecture can remain a central visual feature.
