This individually documented natural Clear Quartz weighs 8.209 carats and has been fashioned into a distinctive cushion-shaped custom cut. Its transparent, almost colourless body allows the geometry of the individual faceting and the natural internal character of the gemstone to remain clearly visible.

Measuring approximately 14.3 × 11.2 × 8.1 mm, the stone has a substantial face-up presence and a softly geometric cushion outline. Rather than following a conventional standardized brilliant or mixed-cut design, the custom faceting gives the gemstone an individual visual character and creates changing internal reflections as the viewing angle and illumination vary.

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

Its almost colourless body places particular emphasis on the facet architecture, internal reflections and surrounding light. Because Clear Quartz is highly transparent and near-colourless, colours from nearby objects, backgrounds and lighting may be reflected or transmitted through the stone. Any coloured flashes visible in photographs or video should therefore be understood as environmental reflections rather than inherent body colour or colour change.

The cutting and symmetry of this specimen are assessed as Fair. These characteristics result in a more individual and less precision-balanced presentation than highly symmetrical commercial cutting, while the transparent material and custom facet arrangement still provide an interesting interplay of light and geometry.

Clear Quartz belongs to the quartz mineral species and is valued for its transparency, durability and versatility in lapidary work. Natural material of this size allows cutters considerable freedom to explore unconventional facet patterns and proportions that differ from standardized calibrated gemstones.

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 inclusions, internal growth structures and 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 8.209 ct weight, transparent near-colourless body and individual cushion custom faceting, this natural Clear Quartz offers a distinctive combination of natural clarity, geometric form and unconventional lapidary character. It is suitable for gemstone collectors, bespoke jewellery projects or display where the individuality of the exact specimen is an important part of its appeal.

Evaluation Notes

This natural Clear Quartz presents a strong overall quality profile, combining high transparency, a clean VS clarity appearance and a distinctive cushion custom cut. The near-colourless body allows the facet geometry and internal reflections to remain clearly visible. Fair cut precision and symmetry limit overall refinement, but the gemstone retains attractive optical character, good visual presence and an individual lapidary identity.
