Natural Clear Quartz · 17.464 ct · Custom Cut

This individually documented natural Clear Quartz weighs an impressive 17.464 carats and has been fashioned into a distinctive octagonal custom cut with concave facets. Its transparent, almost colourless body provides an ideal visual field for the unusual facet architecture, allowing the geometry and depth of the cutting style to become a defining feature of the gemstone.

Measuring approximately 19.2 × 14.0 × 9.1 mm, this is a substantial gemstone with strong visual presence. The elongated octagonal outline gives the stone a structured and contemporary appearance, while the custom faceting moves beyond conventional brilliant or mixed-cut designs.

A particularly notable feature is the use of concave facets. Unlike traditional flat facets, concave faceting introduces curved surfaces into the cutting design. These curved facets can redirect light through the gemstone in complex ways, creating elongated reflections, increased visual movement and a pronounced sense of depth when the stone is viewed from different angles.

The near-colourless nature of the Quartz allows these optical effects to remain especially visible. Rather than body colour dominating the appearance, the eye is drawn toward the interaction between transparency, internal reflections and the custom facet geometry.

The gemstone has a VS clarity profile, presenting good natural transparency while retaining identifiable internal characteristics typical of natural Quartz. These inclusions or growth features form part of the individual character of the stone without preventing light from travelling effectively through the material.

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

Clear Quartz is particularly well suited to experimental and precision lapidary work because sufficiently clean crystals allow cutters considerable freedom in developing unconventional designs. In a larger specimen such as this, concave cutting can produce optical effects and internal reflections that would be considerably less pronounced in smaller material.

As a natural gemstone, internal inclusions, fine growth structures, subtle internal variations or minor surface characteristics may be present. These features originate from the natural formation of the crystal and contribute to the individual identity of the specimen.

With its substantial 17.464 ct weight, transparent near-colourless body and sophisticated concave custom faceting, this natural Clear Quartz offers an unusual combination of scale, geometric design and optical depth. It is particularly suitable for collectors, bespoke jewellery projects or display applications where an individually cut gemstone is preferred over a standardized commercial design.
