5.68 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This 5.68 carat orange moonstone is presented as a translucent oval cabochon measuring 14.05 by 9.90 by 5.45 millimeters, originating from Ceylon, Sri Lanka. The stone has been cut as a domed cabochon to prioritize uniform color presentation and surface luster, with an even, well-centered oval outline and a proportional dome height that balances color saturation and light return. Clarity is graded as very slightly included evaluated at eye level, indicating only minor natural inclusions such as pinpoint and fine platelets that are visible under careful inspection but do not significantly disrupt the visual plane or compromise structural integrity. Color intensity is medium intense, a warm orange hue that is consistent across the table with limited zoning, and the piece displays an excellent polish with a smooth, high-gloss finish that enhances light reflection and perceived depth. No enhancement has been applied, confirming that the body color and surface condition are entirely natural, and provenance from Sri Lanka supports the geological quality typical of Ceylon moonstones.

From a gemological perspective this moonstone benefits from the cabochon execution, which is the preferred cutting style for potassium feldspar specimens to optimize bodycolor and any subtle adularescent effect inherent to the material. The dome geometry has been executed to avoid over-thinning at the edges while maintaining a symmetrical girdle that facilitates secure setting. Typical orthoclase moonstone properties relevant to handling include a refractive index in the approximate range of 1.518 to 1.526 and a specific gravity near 2.56 to 2.62, low birefringence, and moderate hardness that recommends protective mounting. For jewelry design we recommend a bezel setting to protect the perimeter and preserve polish, or a low-profile prong mount aligned with the long axis to showcase the oval silhouette and to maximize face-up color. Routine care should exclude ultrasonic cleaners, aggressive heat, or harsh chemicals, and should consist of gentle cleaning with mild soap and a soft brush.
