17.25 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This listing describes one translucent grey moonstone, weighing 17.25 carats, presented in a classic oval shape with dimensions of 19.65 x 14.61 x 8.47 mm, cut as a cabochon. The cabochon cut provides a smooth domed surface that highlights the stone body and internal light response. Color is classified as grey with medium color intensity, offering a soft neutral tone that is adaptable to a range of metal settings and design styles. The translucency of the material permits a controlled diffusion of light through the body of the stone, which in turn contributes to the subtle optical effect for which moonstone is prized. The overall appearance is even and restrained, with the oval outline producing a balanced visual footprint suitable for a solitaire setting or as a focal element in a multi stone composition.

The stone has been graded at a clarity level of very very slightly included, evaluated at eye level, which indicates that inclusions are minimal and do not materially affect the visual appeal under normal viewing. The cabochon dome has been shaped to optimize the play of light while maintaining consistent thickness across the profile, and the finish has been executed to an excellent polish, providing smooth, reflective surfaces free of noticeable nicks or polish lines. There has been no enhancement applied to this moonstone, the material is natural and untreated, preserving its intrinsic color and internal character. Measurement precision including the carat weight and dimensions was established using standard gemological tools, and the proportions of the oval have been selected to maintain symmetry and to support a secure setting without unnecessary removal of material.

This moonstone originates from Ceylon, Sri Lanka, a well known source that has yielded material with stable color and attractive translucency. The provenance from Ceylon imparts predictable material qualities, including fine grain structure and consistent optical behavior, which are helpful for designers and lapidaries when planning a finished piece. The Natural Gemstone Company has sourced and evaluated this specimen in house, and the description reflects direct observation and standard grading conventions. For practical use, the cabochon form and the moderate size make this specimen suitable for a statement ring, a pendant, or a central element in a bespoke brooch. Recommended mounting approaches include bezel and partial bezel settings to protect the girdle and the dome, and for rings a low profile mount can minimize exposure to knocks. The stone should be handled with care, cleaned with warm water and a mild detergent and a soft brush or cloth, and kept away from harsh chemicals and high heat. Ultrasonic and steam cleaners are not recommended for delicate feldspar materials unless a lapidary has verified the absence of internal stress and fluid inclusions. When stored, the stone should be kept separately from harder gemstones to avoid surface abrasion.

Overall this 17.25 carat oval grey moonstone offers a combination of measured proportions, natural translucency, and an excellent polish, with no enhancement and a clear statement of origin from Ceylon, Sri Lanka. The cabochon profile and medium color intensity provide versatility for a range of design approaches while the very very slightly included clarity grade reflects sound material quality for pieces that emphasize natural character rather than complete optical purity.
