2.90 Ct. Cabochon Moonstone from Madagascar

This transparent 2.90 carat round blue flash moonstone is presented in a classic cabochon cut, with precise dimensions of 9.36 by 9.37 by 4.58 mm, a light color intensity, and an excellent polish. The gem displays a pronounced blue flash that is characteristic of high quality moonstone, and the degree of transparency allows the adularescence to read clearly across the dome. Clarity is graded as very slightly included, evaluated at eye level, which indicates minimal internal features that do not materially affect the visual performance of the stone. There has been no enhancement applied, ensuring the material is in its natural state, and the combination of size, cut, and polish makes this example well suited for use in fine jewelry or as a collector specimen.

The origin of this moonstone is Madagascar, a source recognized for producing feldspar material with notable adularescence and good transparency. Geological conditions on the island favor the formation of large, well-formed feldspar crystals within pegmatitic and metamorphic environments, and stones from Madagascar are often distinguished by a clean body color and a strong, blue oriented flash. Provenance contributes to both the qualitative assessment and market value of a gemstone, by providing context about formation, expected performance, and supply characteristics. For the buyer, a documented origin from Madagascar can mean greater confidence in the stone's visual attributes and its rarity within a given size and clarity range.
