70.57 Ct. Yellow Cabochon Moonstone from Ceylon (Sri Lanka)

One beautiful translucent yellow moonstone of considerable presence, weighing 70.57 carat, is presented in an elegant oval shape with dimensions of 35.22 x 25.23 x 11.30 mm, carefully fashioned as a classic cabochon to showcase its internal light play. The surface displays an excellent polish, and the stone is graded as eye clean when evaluated at normal viewing distance, free of inclusions that would distract from its soft glow. Color intensity is faint, which is typical for high quality Sri Lankan moonstone and allows a delicate, warm yellow body color to harmonize with the adularescent sheen that is the hallmark of moonstone. There is no enhancement to alter its appearance, and the piece retains full natural integrity from its origin in Ceylon Sri Lanka.

From a gemological perspective this specimen merits close attention, especially from an educated buyer seeking both aesthetic and material quality. The cabochon cut is ideal for moonstone, because it maximizes the adularescence created by the microscopic layering of orthoclase and albite feldspar that scatters light, producing a soft internal luminescence rather than a faceted sparkle. The eye clean clarity grade confirms that the stone presents that luminescent effect without internal disruptions at unaided eye level, which improves the perceived clarity and value for applications in high quality single stone settings. The faint yellow tone is subtle and natural, adding warmth without overpowering the adularescence, and the excellent polish enhances surface luster while preserving the integrity of the dome required for a strong floating sheen. At 70.57 carat this moonstone is substantial in size, and large, untreated, eye clean examples from Ceylon are uncommon. For the discerning collector, the combination of size, natural color, intact structure, and superior polish creates a piece that is both visually appealing and technically well prepared for appraisal and bespoke design use.
