17.97 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This listing from The Natural Gemstone Company describes a single, translucent peach moonstone of notable size and quality, offered with full gemological particulars. The stone weighs 17.97 carats, and is fashioned into an oval shape with dimensions of 18.42 x 14.17 x 8.39 mm. The cut is a traditional cabochon, chosen to best display the internal optical phenomena and even color distribution. Clarity is graded as eye clean when evaluated at normal viewing distance, indicating an absence of visible inclusions to the unaided eye. Color intensity is described as medium light, and the surface condition is reported as an excellent polish, which contributes to an overall refined presentation suitable for fine jewelry design and collector storage.

Optical and physical characteristics are presented precisely to aid in evaluation and setting decisions. The gem exhibits the characteristic adularescence associated with quality moonstone, appearing as a soft sheen that moves beneath the surface as the viewing angle changes, enhanced by the smooth cabochon dome. Translucency permits light to penetrate and diffuse within the body of the stone, yielding a warm, even peach hue across the oval outline. The excellent polish produces a clean, reflective surface without noticeable polishing lines, and the cabochon proportions preserve both depth and face up size for a balanced appearance in wearable mounts. The eye clean clarity grade confirms that at eye level the viewer will not encounter distracting internal features, making this specimen visually appealing both loose and set.

Provenance and treatment information is stated clearly, with the origin recorded as Ceylon, Sri Lanka, a well established source for fine feldspar specimens. No enhancements have been applied to this piece, the color and optical effects are natural, and the gem has not undergone heating, irradiation, dyeing, or other common treatments. This untreated status is important for valuation and for clients who prioritize wholly natural material. Practical considerations for use include the mineral hardness and handling. Moonstone typically measures around six to six and a half on the Mohs scale, and while durable enough for many types of jewelry, prudence is advised for everyday wear in high impact settings. Protective mounting such as bezel settings, lower profile rings, or pendants with secure crowns will reduce exposure to knocks and abrasion and help preserve the polished surface and adularescent sheen.

Documentation and application notes are provided to support professional use and consumer confidence. Measurements and weight can be verified upon request, and detailed photographs accompany the description to illustrate color and surface condition under standard lighting. The size and warm peach tone of this 17.97 carat oval cabochon make it well suited to center stone use in pendants and statement rings, and it may also be considered by designers for bespoke pieces where a large, untreated moonstone is desired. For care, cleaning with mild soap, lukewarm water, and a soft cloth is recommended, and exposure to ultrasonic cleaners and harsh chemicals should be avoided. This peach moonstone offers a combination of natural origin, untreated status, pleasing adularescence, and professional finishing, and stands as a representative offering from The Natural Gemstone Company.
