7.15 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One beautiful translucent 7.15 carat oval orange moonstone is presented by The Natural Gemstone Company, with precise dimensions of 14.04 x 10.08 x 6.72 mm. This gem is cut in a classic cabochon, a choice that maximizes the stone response to light, and it carries an excellent polish that produces smooth reflective highlights across the dome. The body color reads as a warm orange with a medium intense color intensity, and the translucency allows for a gentle internal glow without being overly opaque. Visually the stone exhibits the soft, floating luminescence that collectors and connoisseurs expect from fine moonstones, a characteristic that lends both aesthetic appeal and tactile presence when set in jewelry. The lack of enhancement is an important attribute, confirming that the color and surface state are natural, and the origin from Ceylon, Sri Lanka, links this specimen to one of the most respected historical sources for high quality feldspar gems.

From a gemological perspective this moonstone belongs to the feldspar group, and it displays the adularescence that is emblematic of moonstones, an optical phenomenon produced by thin alternating layers of albite and orthoclase that scatter light to create a soft sheen. The cabochon cut is deliberately used to reveal this effect, and the excellent polish ensures minimal surface disturbance to the light reflection. Clarity has been evaluated at eye level as very slightly included, a practical grading that informs the buyer that inclusions are minimal and do not detract from the visual performance under normal viewing conditions. Many collectors prefer stones that read clean to the unaided eye, and this piece meets that expectation while still retaining natural internal character when examined under magnification. The medium intense color is balanced and versatile, suitable for a range of metal choices and design approaches, and since no heat treatment or dyeing has been applied, the gem retains full natural provenance.

For the educated buyer the value proposition of this orange moonstone rests on several verifiable factors, starting with the combination of carat weight, color, clarity, cut, and origin. A 7.15 carat weight for a moonstone with these dimensions is substantial, and the oval cabochon shape is highly desirable for both bespoke and classic settings. Orange or peach toned moonstones are less common than the colorless to bluish adularescent varieties, and their warm body color can appeal to collectors seeking rarity and distinctiveness. The Sri Lankan origin further enhances desirability, as Ceylon has a long reputation for producing feldspar specimens with attractive body color and clean crystallography. The untreated nature of the gem is crucial for valuation and ethical purchasing, it confirms that the color is entirely natural, and it simplifies future resale or certification. Typical gemological parameters for orthoclase moonstone include a refractive index in the range of 1.518 to 1.526 and a specific gravity around 2.56 to 2.60, data points that laboratories use to confirm identity, and this moonstone conforms to expected properties for a fine Sri Lankan specimen.

Practical considerations for use and care complete the profile of this item, and they are important for anyone planning to set it in jewelry. Moonstone is a feldspar with a Mohs hardness around 6 to 6.5, therefore it requires thoughtful mounting to protect the cabochon from sharp knocks and abrasive contact. A bezel setting or protective halo are attractive and functional choices that preserve the polished dome and reduce the risk of chipping. Routine cleaning with warm water, mild soap, and a soft brush is recommended, and harsh chemicals or ultrasonic cleaners should be avoided to maintain the natural surface luster. At The Natural Gemstone Company we provide detailed provenance information and can arrange independent gemological certification upon request, giving an extra level of assurance to collectors and jewelers. This orange moonstone combines natural origin, substantial weight, pleasing translucency, and an excellent finish, making it an appealing acquisition for those who value authenticity and classic gemological quality.
