2.00 Ct. Cabochon Moonstone from Madagascar

This transparent 2.00 carat round blue flash moonstone measures 8.73 x 8.67 x 3.65 mm and is presented in a cabochon cut. The gem carries a clarity grade of very slightly included, evaluated at eye level, and exhibits a light color intensity with an excellent polish. There are no enhancements, and the stone is sourced from Madagascar. The rounded outline and near equal diameter dimensions reflect careful cutting and grading, contributing to a balanced appearance suitable for a range of mounting styles. The Natural Gemstone Company provides this moonstone with standard gemological information and consistent finishing quality.

The cabochon cut is the decisive factor in how this moonstone displays its blue flash and internal light phenomena. Moonstone generates adularescence through layered feldspar structures that scatter light within the crystal. A smooth domed surface and well controlled dome height, as present in this specimen, concentrate incident light and allow multiple internal reflections to coalesce into a coherent schiller effect. The 3.65 mm depth provides sufficient thickness to interact with light across the lamellar planes while maintaining transparency that permits the blue flash to travel unimpeded to the viewer. The very slight inclusions, seen only at eye level, do not significantly disrupt internal light paths, and the excellent polish minimizes surface scatter, producing a clean, defined sheen. The round cabochon symmetry ensures that the blue adularescence moves consistently as the stone is rotated, rather than appearing patchy or directional. In practical terms, the cut maximizes the inherent optical properties of the moonstone, making the blue flash readily perceptible under varied lighting, while the combination of transparency, proportion, and polish preserves the quality and durability expected by professional setters and discerning collectors.
