This natural Moonstone is an impressive 11.583 carat cushion-shaped cabochon displaying a strong and highly attractive rainbow adularescence across its milky white body. Under directional light, the gemstone reveals shifting flashes of blue, green, yellow and warm orange tones that move across the surface as the viewing angle changes.
Measuring approximately 13.1 × 11.2 × 7.7 mm, the stone has a substantial presence and a generous cabochon depth, allowing the internal optical effect to develop with strong visual impact. Its softly rounded cushion outline gives the gemstone a balanced and elegant appearance, making it particularly suitable for a statement ring, pendant or bespoke jewellery design.
The body colour ranges from milky white to softly translucent, with natural internal structure visible beneath the polished surface. The stone shows internal veils, layered feldspar features and subtle variations in transparency that contribute directly to its characteristic adularescence.
Its most distinctive feature is the multicoloured optical display. Depending on the angle and intensity of the light, the sheen shifts between predominantly blue and green areas with additional yellow, peach and orange reflections. This rainbow effect gives the stone considerably more visual complexity than Moonstones displaying only a single blue sheen.
The cabochon has been polished to enhance both the smooth surface lustre and the internal optical response. The natural internal structure remains visible, preserving the individual character of the gemstone.
No indications of treatment are observed. The stone is a natural, untreated Moonstone, with its colour, internal characteristics and rainbow adularescence resulting from its natural feldspar structure.
