13.16 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One translucent peach moonstone is offered through The Natural Gemstone Company, an oval shape cabochon weighing 13.16 carats. The piece measures 16.80 by 12.49 by 8.08 millimeters, dimensions that make it well suited to a variety of jewelry applications where a prominent yet elegant presence is desired. The stone originates from Ceylon, Sri Lanka, and has been recorded as receiving no enhancement. Its overall presentation is consistent with natural, untreated material, exhibiting a soft, even peach tone with a gentle internal glow that is characteristic of quality moonstone specimens.

The gem has been examined at eye level and assigned a clarity grade of very very slightly included, reflecting only minor internal features that do not detract from its visual appeal under normal viewing conditions. Color intensity is described as medium light, offering a balanced peach saturation that remains delicate without appearing washed out. The cabochon cut has been executed to emphasize surface luster and internal optical phenomena, and the polish has been graded excellent, resulting in a glossy, mirror like finish across the dome. The stone is translucent rather than transparent, which contributes to a subtle depth and soft diffusion of light rather than sharp internal reflections.

Optically, this moonstone displays the characteristic adularescence formed by the intergrowth of feldspar layers, producing a soft, billowing sheen that migrates as the stone or the light source is moved. In this specimen the adularescent sheen is gentle and well centered beneath the dome, complementing the peach body color and enhancing perceived depth. The cabochon profile is proportioned to maintain structural integrity while maximizing the visible optical effect, making the gem particularly suitable for pendants and earrings where the dome can be appreciated without excessive wear. For rings a protective setting is recommended, such as a bezel or low profile mounting, to minimize exposure to knocks and abrasion given the stone hardness around six to six and a half on the Mohs scale.

Handling and care recommendations reflect the material properties and aim to preserve the quality of the cabochon. Routine cleaning should be performed with warm water, a mild detergent and a soft brush, followed by careful drying with a soft cloth. Strong acids, alkaline cleaners, prolonged exposure to heat and ultrasonic or steam cleaning methods are not recommended, in order to maintain the surface polish and to avoid stress on internal structures. When set, the stone should be inspected periodically to ensure secure mounting, and when not being worn it should be stored separately from harder gemstones and metals to prevent surface scratching.
