Natural Moonstone · 6.393 ct · Cushion · Mixed Cut

This individually documented natural Moonstone weighs 6.393 carats and has been fashioned into a substantial cushion-shaped mixed cut. The gemstone displays a clear to slightly white body appearance with a subtle blue adularescence, creating a delicate floating sheen that becomes visible as the stone is viewed under changing light and from different angles.

Measuring approximately 11.9 × 10.3 × 8.8 mm, this specimen has strong visual presence and a balanced cushion outline. The mixed facet arrangement allows the natural transparency of the material to remain prominent while producing changing internal reflections across the stone.

The gemstone is transparent and has a clarity profile comparable to I1, with natural inclusions and internal growth features visible within the material. These characteristics form part of the natural feldspar structure and contribute to the individual identity of the stone without preventing the adularescent effect from remaining visible.

A defining feature of this specimen is its slight blue adularescence. This optical phenomenon appears as a soft bluish sheen that seems to move beneath the surface as the gemstone is tilted. The effect is associated with the internal layered structure of Moonstone and provides a distinctive contrast against the otherwise clear to slightly white body colour.

The overall cutting quality is assessed as Very Good, with Very Good symmetry supporting a well-balanced face-up appearance. The Good to Very Good polish and Good luster further enhance the clarity of the facet junctions and the visual presentation of the gemstone.

Moonstone belongs to the feldspar group and has a hardness of approximately 6 on the Mohs scale. Transparent material suitable for faceting is less common than the more opaque or translucent material typically used for cabochons, making faceted Moonstone particularly interesting when the material retains both transparency and visible adularescence.

As a natural gemstone, internal inclusions, fine lamellar growth structures, subtle internal variations and minor surface-reaching features may occur. These characteristics are part of the geological formation of the material and may influence the visibility and distribution of the adularescent sheen.

With its substantial 6.393 ct weight, transparent body, balanced cushion faceting and subtle blue adularescence, this natural Moonstone offers an attractive combination of optical character, size and individual feldspar structure. It is particularly suitable for collectors, bespoke jewellery projects or distinctive centre-stone designs.
