5.11 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This listing describes one natural blue flash moonstone, cabochon cut, weighing 5.11 carats, with an oval outline and dimensions of 10.32 x 9.28 x 6.72 mm. The gem is opaque with a cool white body color and a distinct blue adularescence that appears as a soft flash when viewed at different angles. Clarity is graded as very slightly included, evaluated at eye level, with minor internal features that do not detract from the overall visual effect. Color intensity is classified as light, and the surface exhibits an excellent polish that enhances the stone s luster and the movement of the blue flash across the dome. There has been no enhancement to this material, and the piece originates from Ceylon Sri Lanka.

The cabochon profile and dimensions make this moonstone well suited for a variety of jewelry applications, including bezel set rings, pendants, and earrings, where the dome can be displayed to best effect. As with all feldspar group gemstones, care should be taken to avoid prolonged exposure to sharp blows and to harsh chemical cleaners, and routine cleaning with a soft cloth and warm soapy water is recommended. The combination of a well executed cabochon shape, consistent polish, and natural blue adularescence gives this specimen both visual appeal and practical versatility for design use. For transparency and provenance, this stone is offered with full disclosure of origin and treatment status by The Natural Gemstone Company, and it is presented as a natural, untreated moonstone from Sri Lanka, suitable for collectors and designers who prioritize material integrity and classic optical character.
