This individually documented natural Clear Quartz weighs 10.803 carats and has been fashioned into a distinctive cushion-shaped custom cut. Its almost colourless, transparent body gives the gemstone a clean and refined appearance while allowing the individual facet architecture to remain clearly visible.

Rather than following a conventional brilliant or standard mixed-cut pattern, this specimen features an individual custom faceting design. The elongated and geometric facet arrangement creates a distinctive play of reflections across the stone and gives the gemstone a visual identity that differs from more traditional commercial cutting styles.

The transparency of the quartz allows light to move freely through the stone, highlighting both its internal clarity and the structure of the cut. Because the stone is almost colourless, the visual emphasis falls strongly on facet interaction, light return and the changing geometric reflections produced as the gemstone is viewed from different angles.

Clear Quartz belongs to the quartz mineral species and is valued for its transparency, durability and versatility in lapidary work. Large, clean specimens can provide cutters with considerable freedom in developing unusual or individually designed faceting patterns, making the material particularly suitable for custom cutting.

As a natural gemstone, this Clear Quartz may show minute internal inclusions, subtle growth features or minor surface characteristics. Such features form part of the individual geological history of the material and help distinguish natural gemstone material from highly standardised synthetic or manufactured alternatives.

Its combination of substantial size, clean transparent appearance and unconventional custom cutting makes this gemstone especially suitable for collectors, bespoke jewellery projects or designs requiring a distinctive centre stone rather than a standardized calibrated gem.

This is an individual natural gemstone, and the exact Clear Quartz shown in the accompanying photographs and documentation is the specimen that will be supplied.
