1.19 Ct. Blue Flash Cabochon Moonstone from Ceylon (Sri Lanka)

At The Natural Gemstone Company I am pleased to introduce a moonstone that speaks to the long, luminous conversation between humanity and the night sky, one beautiful translucent 1.19 carat oval shape blue flash moonstone, with dimensions of 8.12 x 6.13 x 3.19 mm. This gem is cut en cabochon, a timeless cutting style that has been used for centuries to showcase optical phenomena, and the polished dome of this piece reveals a serene blue adularescence that floats across the surface like moonlight on water. Sourced from Ceylon Sri Lanka, an island with a storied history of producing some of the world most treasured gems, this moonstone carries both geographical pedigree and artisanal care. The clarity grade is eye clean when evaluated at eye level, the color intensity is near colorless, and the polish is excellent, allowing the blue flash to emerge with a soft, ethereal glow. No enhancement has been applied to alter its natural beauty, so what you receive is an honest, natural phenomenon that has been carefully selected and finished to honor the stone s own voice, rather than to change it.

Moonstone has been admired since antiquity, worn by Roman and Greek civilizations, cherished in Indian lore as a sacred stone imbued with lunar energies, and used in Victorian and Edwardian jewelry for its romantic, feminine allure. The cabochon cut of this 1.19 carat oval recalls those classic settings, designed to maximize the internal shimmer rather than faceted sparkle, and it lends itself beautifully to heirloom designs that will travel from generation to generation. The translucent body with near colorless tone allows your choice of metal and setting to dictate mood, silver or white gold to emphasize the cool lunar blue, yellow gold to add warm antique contrast, or rose gold for a dreamy, vintage inspired palette. Imagine this gem set as a central stone in a delicate ring bezel, cradled in a protective, rounded frame, or mounted as a pendant where the motion of the wearer can awaken the stone s inner light, revealing the blue flash from different angles.

When selecting moonstone for everyday wear, durability is an important consideration, and comparing Mohs hardness ratings helps to set expectations for use and care. Moonstone registers at about 6 to 6.5 on the Mohs scale, which places it softer than quartz that sits at 7, and significantly softer than corundum varieties such as sapphire and ruby that are 9, and much softer than diamond which is 10. It is harder than calcite at 3 and a touch more resilient than apatite at 5, but the relative softness means moonstone can show wear more readily than harder gems, and it benefits from thoughtful settings and occasional gentle care. For a gem like this translucent cabochon, which is eye clean and highly polished, protective settings such as a bezel or a low halo help reduce the risk of accidental chips and abrasions, especially in rings worn daily. For wearers who prefer more exposed settings, placing this moonstone in a pendant or earrings offers both visibility and a reduced likelihood of impact, because pendants hang and earrings move more freely away from hard surfaces.

Caring for this blue flash moonstone is straightforward, and consistent with practices that have preserved delicate gems for centuries, combining gentle handling with a respect for its natural character. Clean with warm soapy water and a soft cloth, rinse well, and avoid ultrasonic and steam cleaning which can be stressful for stones with internal layering and adularescence. Avoid exposure to harsh chemicals and sharp knocks, and remove the piece for heavy manual work or extreme sports, so the stone s surface and dome remain pristine and the excellent polish is maintained. At The Natural Gemstone Company we are committed to sourcing and presenting stones in their natural state, and this moonstone s no enhancement origin from Ceylon Sri Lanka, eye clean clarity, excellent polish, and classic cabochon shaping make it an ideal selection for collectors and designers who value history, subtlety, and endurance. This little oval of moonlit blue invites a microcosm of heritage and craftsmanship into your collection, a timeless piece ready to be set, worn, and loved for years to come.
