2.24 Ct. Cabochon Moonstone from Madagascar

This transparent 2.24 carat round blue flash moonstone originates from Madagascar, and measures 8.22 by 8.20 by 4.97 mm. The gem is fashioned as a cabochon, a shape and cut chosen to maximize its characteristic adularescence, and it presents a light color intensity with a notable blue flash. Clarity is graded as very slightly included when evaluated at eye level, and the surface shows an excellent polish. There has been no enhancement applied to this stone, and its transparency allows the internal interplay of light to be clearly observed. The cabochon dome and precise polishing serve to reveal the layered microstructure that produces the moonstone effect, creating a luminous, floating sheen across the face of the gem rather than the faceted sparkle associated with other gem types.

Compared to more common gemstones, this moonstone offers a different optical experience that can be described in technical terms. Diamonds and other highly refractive, faceted gems derive their visual impact from brilliance and fire, which are produced by strong refraction and dispersion within a faceted geometry, resulting in scintillation and pronounced flashes of spectral color. Sapphires and emeralds, when faceted, emphasize color saturation and luster, with light returning to the eye as crisp, angular reflections. By contrast, the visual appeal of this blue flash moonstone derives from adularescence, the soft, directional sheen caused by light scattering from microscopic lamellae within the host orthoclase or albite structure. The effect is a diffuse, silky glow that appears to move under changing light and viewing angles, and in this specimen the combination of transparency, a high quality cabochon cut, and excellent polish produces a particularly clean and striking blue adularescence. The very slightly included clarity at eye level means the effect is not obscured by internal features, and the absence of enhancement preserves the natural character of the phenomenon. With a Mohs hardness in the mid single digits, this moonstone is best set in protective mountings for rings and worn with moderate care, and The Natural Gemstone Company provides this detailed grading and origin information to support informed selection and long term enjoyment.
