13.29 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

I am pleased to present a gorgeous grey moonstone offered by The Natural Gemstone Company, a single translucent oval cabochon, weighing 13.29 carats, with elegant proportions that will suit a wide range of jewelry designs. The gem measures 15.95 by 11.97 by 9.27 millimeters, and it has been expertly shaped into an oval cabochon to maximize its internal light play and surface reflection. The transparency is described as translucent, and the color intensity is very light grey, which gives this stone a soft and versatile appearance. The clarity grade has been evaluated at eye level as very slightly included, a quality that provides character without affecting the gemological integrity, and the polish has been rated as excellent, producing a high degree of brilliance across the dome of the cabochon. There has been no enhancement applied to this moonstone, and its origin is Ceylon Sri Lanka, a source known for producing fine quality moonstones with attractive adularescence.

Visually this moonstone presents a serene and subtle adularescence that shimmers beneath the surface as light moves across the cabochon, a hallmark of fine moonstone that collectors and designers alike prize. The very light grey body color acts as an elegant canvas for this glowing internal sheen, and because the stone is translucent the light interaction appears soft and cloudlike, enhancing the gem with a calming optical effect. The cabochon cut accentuates the moonstone character, providing a convex top that catches and releases light smoothly, which is especially desirable in rings, pendants, and statement earrings where the dome can be shown to best effect. The size and weight at 13.29 carats make this a substantial gem that maintains wearability, and the oval outline offers design flexibility, whether set vertically or horizontally, or used as the centerpiece in a bespoke piece.

From a design perspective this moonstone is an exceptional candidate for a variety of settings, and as your consultant from The Natural Gemstone Company I recommend considering bezel and prong mounting options to complement the cabochon profile. A simple bezel can protect the sides of the stone and emphasize the smooth dome, producing an understated and durable piece that is ideal for daily wear. A delicate prong setting can lift the gem subtly, allowing more light to interact with the base of the cabochon and enhancing the adularescence, which is especially attractive when the stone is suspended in a light pendant or set atop a low profile ring head. For a more contemporary look consider a mixed metal design, where warm yellow gold accents can contrast the cool grey tone, or cool white metals can create a monochromatic and modern presentation. The dimensions will accommodate both classic and modern designs, and the comfortable depth of nine point two seven millimeters provides enough presence without becoming cumbersome.

Regarding provenance and care this moonstone comes from Ceylon Sri Lanka, and it has not been treated in any way, which assures collectors and connoisseurs that the gem is presented in its natural state. The absence of enhancement preserves the integrity of the gem, and the very slightly included clarity at eye level is a natural characteristic that does not detract from the beauty or durability of the stone. To preserve the polish and surface quality I recommend avoiding prolonged exposure to harsh chemicals and extreme temperatures, and to clean the moonstone gently with warm soapy water and a soft brush, rinsing thoroughly and drying with a soft cloth. Ultrasonic cleaners and steam cleaning should be avoided due to the potential for internal fractures in some feldspar group minerals. When storing this cabochon keep it separate from harder gems to prevent scratches, and consider a padded compartment or a soft pouch. For certification or appraisal services The Natural Gemstone Company is able to provide detailed documentation on request, including origin information and a transparent report of the gemological attributes.
