1.83 Ct. Moonstone from Madagascar

This semi transparent 1.83 carat round rainbow moonstone from Madagascar presents a balanced combination of size and optical character that will appeal to an educated collector. Cut to a mixed brilliant style, this gem measures 7.59 by 7.32 by 6.41 mm, and has been finished with an excellent polish that maximizes surface luster while preserving the internal play of light. Clarity is graded very slightly included, evaluated at eye level, which for moonstone is a desirable state because it means the stone remains effectively eye clean while retaining the natural internal features that create its signature adularescence. Color intensity is light, allowing the cool blue and spectral flashes to read cleanly against the stone body without overpowering the gem, and enhancement is none, confirming that what you see is entirely natural and untreated. The Natural Gemstone Company offers this piece with provenance from Madagascar, a source renowned for producing moonstones with pronounced adularescence and stable material suitable for fine jewelry.

What truly distinguishes this example are the unique inclusions that give it an unmistakable signature, and that also serve as reliable markers of natural origin. The adularescent sheen originates in the stone from submicroscopic, lamellar layering of feldspar components, and in this specimen you can observe delicate platelet and needle like inclusions that scatter light into subtle rainbow flashes. These fine internal features are dispersed in a way that creates a layered, floating band of light when the gem is moved, and occasional tiny reflective platelets produce intermittent spectral color that is especially visible under directional light. To the trained eye these inclusions are not detractions but signatures of authenticity, telling a story of natural growth and exsolution processes that cannot be replicated by simple treatments. For the educated buyer this moonstone represents a desirable combination of natural origin, clarity and optical intrigue, ready to be set into a design that showcases its adularescence, or held in a collection as an example of high quality Madagascan material.
