15.76 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

Introducing a lovely natural moonstone offered by The Natural Gemstone Company, a semi translucent grey moonstone weighing 15.76 carats, cut in an elegant oval cabochon shape. The gem measures 18.57 by 15.10 by 8.19 mm, and the smooth domed cabochon enhances its classic moonstone character. This piece displays a medium light color intensity that reads as a soft, silvery grey with subtle creamy undertones, and the polish is excellent which gives a bright, satiny surface. Clarity has been evaluated at eye level as very slightly included, which means the gem appears clean to the eye while retaining natural internal features that speak to its authenticity. There has been no enhancement to this stone, and its origin is Ceylon Sri Lanka, a source renowned for producing fine moonstones with refined adularescent effects.

Visually the moonstone presents a gentle inner glow, often described as adularescence, that appears to drift across the dome when the gem is moved in light. Because the cabochon has been carefully shaped and highly polished, the adularescence is smooth and even, and the semi translucency allows a soft diffusion of light from within. The grey tone is versatile, shifting slightly with viewing angle and lighting from a cooler silver to a warmer stone like pale ivory, and this dynamic character makes the gem quietly captivating. The very slight inclusions are typical of natural moonstone material and do not detract from the gem’s overall beauty, instead they affirm that this is a natural, untreated stone. The sizable carat weight and substantial depth give the gem presence and a tactile allure that works well in designs where the moonstone is meant to be the central visual focus.

For design and setting considerations this moonstone lends itself to a variety of jewelry styles, from classic solitaire pendants and statement rings to elegant drop earrings. The dimensions and sizeable dome mean the stone sits prominently in a bezel set, which protects the cabochon while showing its full surface, and a low claw or partial bezel mount will also allow the adularescence to be fully appreciated. Pairing suggestions include warm metals such as rose gold to bring forward cream undertones, or cool metals such as white gold or sterling silver to emphasize the grey and silver aspects of the stone. Accent stones such as small diamonds or white sapphires can frame the moonstone without overpowering it, and a simple halo will add a touch of sparkle while keeping attention on the moonstone’s luminous face. With an 18.57 by 15.10 mm footprint and an 8.19 mm depth, the gem is substantial enough for a bold piece yet still elegant and wearable for everyday use when set appropriately.

When considering care and provenance, this moonstone from The Natural Gemstone Company is a natural, untreated gem that should be handled with thoughtful care to preserve its polish and adularescence. Clean the stone gently with warm soapy water and a soft brush, rinse well and dry with a soft cloth, and avoid exposure to harsh chemicals, prolonged heat, or sudden temperature changes. Ultrasonic and steam cleaning are not recommended for moonstone specimens that contain natural inclusions, and protective settings and mindful wear will help prevent scratches and knocks.
