Natural Moonstone · 4.789 ct · Cushion · Mixed Cut

This individually documented natural Moonstone weighs 4.789 carats and has been fashioned into an elegant cushion-shaped mixed cut. The gemstone displays a clear to slightly white body appearance with a subtle blue adularescence, creating a soft bluish sheen that becomes visible as the stone is moved under changing light and viewing angles.

Measuring approximately 12.0 × 10.1 × 6.9 mm, this is a substantial faceted Moonstone with a balanced cushion outline and attractive visual presence. The mixed facet arrangement allows the natural transparency of the material to remain visible while also creating changing reflections across the surface and interior of the gemstone.

The stone is transparent and has a clarity profile comparable to I1, with natural internal inclusions and structural features readily visible within the material. These internal characteristics form part of the natural feldspar structure and may interact with light as the gemstone is viewed from different directions.

A defining feature of this specimen is its slight blue adularescence. This optical effect appears as a delicate bluish reflection or floating sheen rather than a strongly saturated flash, giving the gemstone a refined and individual appearance. The effect results from light interacting with microscopic structural layers within the feldspar.

Moonstone belongs to the feldspar group and is valued for this characteristic optical phenomenon. While Moonstone is commonly fashioned as a cabochon to maximise adularescence, transparent material can also be faceted, producing a different visual character in which both the internal structure and facet geometry contribute to the overall appearance.

As a natural gemstone, this Moonstone may display visible inclusions, fine lamellar structures, subtle internal variations or minor surface-reaching features. These characteristics reflect the geological formation of the material and contribute to the individual identity of the stone.

With its 4.789 ct weight, transparent body, faceted cushion form and subtle blue adularescence, this natural Moonstone offers an attractive combination of optical character, natural internal structure and individual cutting style for gemstone collectors or bespoke jewellery projects.
