10.61 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

Thank you for considering this exceptional gemstone from The Natural Gemstone Company, a beautiful translucent grey moonstone that combines subtle elegance with substantial presence. This is a single 10.61 carat oval shaped specimen, presented with precise dimensions of 16.86 by 13.16 by 6.29 millimeters. The gem is fashioned as a cabochon, which showcases the stone with a smooth rounded dome that optimizes its optical effects. Clarity is graded as very very slightly included when evaluated at eye level, indicating that the stone is clean to the unaided eye with only the most minor internal features visible under magnification. Color intensity is described as intense, offering a strong and consistent grey tone that reads as sophisticated and versatile under many lighting conditions. The polish is excellent, providing a high gloss surface that enhances both the body color and the internal light movement. There is no enhancement, and the origin of this moonstone is Ceylon Sri Lanka, a source renowned for producing high quality feldspar gems. This combination of weight, cut, clarity, color, polish, and natural origin makes this piece a compelling choice for collectors and designers alike.

Visually, this grey moonstone presents as a serene lustrous oval, with a soft translucency that invites careful viewing. The cabochon cut creates a gentle dome that allows light to pass into the stone and reveal subtle internal activity. In many lighting angles you will notice a delicate sheen that moves beneath the surface, a characteristic play of light often referred to as adularescence, which is one of the signature attractions of moonstone. The intense grey body color provides a modern and elegant backdrop for that sheen, allowing it to present with quiet sophistication rather than overt flash. Because the clarity is very very slightly included, the stone preserves a clean visual field that does not distract from the optical movement, while the excellent polish gives reflective highlights along the dome that accentuate the stone in finished jewelry. At 10.61 carats and the dimensions noted, the stone will make a bold pendant, a statement ring, or a striking center for an artisan cuff or brooch. Designers will appreciate the balanced proportions, and collectors will value the combination of size and visual quality.

From a gemological and provenance perspective, the Ceylon Sri Lanka origin is meaningful. Sri Lanka has long been a respected source for quality feldspar gemstones, and moonstones from this region often exhibit fine body tone and clean character. The absence of any enhancement is important for discerning buyers who prefer untreated, natural material, especially for pieces that emphasize geological authenticity. The very very slightly included clarity grade communicates that at normal viewing distances the stone appears clean, which enhances its desirability for both display and wear. The cabochon shape was chosen to maximize the stone character, and the excellent polish was executed to professional standards to ensure smoothness and uniform luster. For settings, a bezel mount will protect the cabochon while offering a contemporary look, alternatively a secure prong setting with protective shoulders can give a more open appearance that lets light interact with the dome. Because of the size and presence of this gem, it can also serve as the focal point in bespoke designer pieces where the metalwork complements the cool grey tone, such as platinum white gold or oxidized silver.

Caring for this moonstone is straightforward, and will help preserve its beauty for years. Avoid exposure to strong heat and harsh chemicals, remove the jewelry before heavy physical activity, and clean the gem with warm soapy water and a soft brush or cloth, rinsing thoroughly and drying gently. For storage keep the moonstone separate from harder gems that could scratch the surface, wrapped in a soft cloth or housed in a padded jewelry box.
