11.34 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This translucent grey moonstone weighs 11.34 carat, and is fashioned into an elegant oval shape with dimensions of 16.63 x 11.71 x 7.61 mm, presenting a classic scale that works equally well as a centerpiece for a ring or as the focal stone in a pendant. The gem has been cut as a cabochon to maximize its adularescence, the soft, floating play of light that defines fine moonstone, and it displays a light color intensity that is subtle and refined. Clarity has been evaluated at eye level, and the stone is graded eye clean, which means no inclusions or features are visible to the naked eye under normal viewing conditions. The polish is excellent, indicating a high quality finish that enhances surface luster and allows the internal sheen to move freely across the dome of the cabochon. There has been no enhancement applied to this gem, it is entirely natural, and it is identified as originating from Ceylon Sri Lanka, a region long respected for producing some of the world s most desirable moonstones.

For an educated buyer, several technical attributes distinguish this stone as a quality acquisition. Moonstone is a member of the feldspar family, and the optical effect called adularescence is produced by microscopic lamellar intergrowths of orthoclase and albite, which scatter light in a way that creates the gem s trademark glow. The cabochon cut is the traditional and preferred shape for exhibiting that effect, and the oval geometry of this piece provides a balanced area for light to travel and reflect. The eye clean clarity grade, evaluated at eye level, removes concerns about visible inclusions that can distract from the adularescence or weaken the gem structurally. The light color intensity maintains a neutral, versatile tone, which is often preferred by connoisseurs who value stones that harmonize with a range of metals and design styles. The combination of natural origin, absence of treatment, and an excellent polish makes this moonstone attractive both to collectors who prioritize provenance and to jewelers seeking a stone that will wear well in a fine setting.

The provenance of this stone from Ceylon Sri Lanka adds meaningful cultural and historical context that enhances its appeal. Sri Lanka has a long heritage of producing feldspar gemstones, and moonstones from this island have been prized for centuries for their clarity and luminosity. Traditionally, moonstones have held a respected place in South Asian and Mediterranean jewelry practices, where they were used as talismans, worn for protection during travel, and given as ornaments to mark auspicious life events such as marriages and new beginnings. In classical lore across Europe and Asia, the moonstone has been associated with the moon and the cycles of change, and it has been used in ceremonial jewelry and heirloom pieces passed down through generations. At The Natural Gemstone Company we emphasize this heritage, and we present this stone not only as a material of beauty, but as a link to traditional uses that confer symbolic resonance. For buyers who value stories as well as specifications, this moonstone offers the tactile and metaphoric qualities that make a gem an heirloom.

From a practical standpoint this moonstone is ready for incorporation into bespoke jewelry, and it is particularly well suited to settings that preserve its cabochon surface and allow light to interact with the dome. We recommend setting styles that protect the girdle and avoid sharp prongs that might expose the stone to impact, and we advise gentle cleaning with warm soapy water and a soft cloth, avoiding steam and harsh chemicals. The Natural Gemstone Company stands behind the authenticity and origin of this gem, and we can provide further details about sourcing, gemological evaluation, and historical context on request. For collectors seeking a natural, untreated, eye clean specimen with classic adularescence and Sri Lankan provenance, this 11.34 carat oval grey moonstone is a compelling choice that bridges technical quality and cultural heritage.
