4.43 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This listing describes a single, translucent blue flash moonstone, weight 4.43 carats, in an oval cabochon cut. Exact dimensions are 10.61 by 8.65 by 5.92 millimeters, providing a balanced face-up presentation and comfortable proportions for a range of jewelry applications. The piece exhibits faint body color with a prominent blue adularescence that appears as a soft, mobile flash across the dome when viewed under directional light. Clarity has been assessed as very very slightly included at eye level, and the surface finish is an excellent polish that enhances the stone’s sheen and visual depth. For inventory and cataloging purposes the opal type field is recorded as White Opal, and the stone is offered with no enhancements. Origin is documented as Ceylon, Sri Lanka, and the item is presented by The Natural Gemstone Company.

Inclusions within this moonstone are natural and modest in extent, and they serve as reliable internal signatures that add to the gem’s individuality. Under magnification and to the unaided eye in most lighting conditions the inclusions present as subtle growth lines and faint veil-like features with rare pinpoint or minute feathering. These internal characteristics do not detract from the gem’s overall translucency or its adularescent effect; rather they interact with light to create depth and to localize the blue flash in a manner that is distinctive to this specimen. Inclusions are commonly used by gemologists and experienced buyers as unique identifiers, comparable to a fingerprint, and they can assist with future identification, matching, or provenance verification without altering the stone’s visual appeal.

From a design and setting perspective the cabochon cut and the generous dome of this moonstone emphasize the adularescence, making the blue flash the focal attribute. The oval proportions and the modest thickness lend themselves well to both ring and pendant designs, and the measured height offers sufficient depth to showcase movement of the flash without making the piece overly bulky. Given moonstone’s typical Mohs hardness around 6 to 6.5, consideration toward protective settings is recommended; bezel settings or partially encircling mounts will protect the cabochon edges while still exposing the dome for light interaction. The combination of excellent polish, translucent body, and very very slight inclusions ensures a visually appealing stone that behaves consistently in different lighting environments, with the blue shimmer becoming more pronounced when the piece is tilted or moved.
