6.55 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One beautiful translucent 6.55 carat oval shape brown moonstone is offered by The Natural Gemstone Company, presented in a classic cabochon cut that emphasizes the gem character and internal light movement. The piece measures 11.31 by 7.41 by 10.02 millimeters, a proportion that balances a broad face with a pleasing dome height suitable for secure mounting or display. The body color reads as a soft brown with light color intensity, producing a warm, earthy tone that is unusually refined for moonstone specimens, and the overall translucency allows gentle diffusion of light rather than complete opacity. This combination of weight, dimensions, and translucency makes the gem versatile for both collector pieces and handcrafted jewelry applications where a substantial cabochon presence is desirable. The gem originates from Ceylon, Sri Lanka, a classic source for feldspar group gems, and it arrives to you with no enhancement, a point of interest to buyers focused on natural, untreated material.

From a grading perspective the stone is evaluated with a clarity grade of very slightly included, assessed at eye level, which indicates that inclusions are present but do not interfere with the gem s overall appearance to an unaided observer. In moonstone these inclusions are typically microscopic platelets, exsolution textures, or thin growth zones that produce or modulate the adularescence rather than detract from it. The cabochon cut is a critical choice for moonstone because it maximizes the surface area from which adularescent sheen or a soft glow can originate, and the excellent polish achieved on this specimen enhances the silky play of light across the dome. Technical properties relevant to handling and setting include the fact that moonstone belongs to the orthoclase feldspar group, with a hardness around 6 to 6.5 on the Mohs scale and a perfect cleavage in one direction, so careful mounting is recommended to protect against sharp impacts and pressure during setting.

For an educated buyer the value proposition of this brown moonstone is rooted in several objective factors, beginning with its natural origin from Ceylon, which carries historical and market recognition for quality feldspar specimens. The gem s untreated status conveys authenticity and preserves potential resale or investment value, since clarity of origin and the absence of enhancements are increasingly important in secondary market transactions. The light color intensity and translucency combine to offer a more subtle aesthetic compared with strongly colored or heavily adularescent stones, appealing to collectors who prioritize varietal rarity and understated elegance. The gem s size at 6.55 carats and the substantial dome make it attractive for bespoke rings and pendants, where the gem can be displayed prominently, and the very slightly included clarity grade means the surface face will read clean to the naked eye while still maintaining the gem s natural character under magnification. Practical considerations that educated buyers will appreciate include the recommendation for protective settings such as bezels or low prong configurations that reduce stress at the edges, and avoidance of harsh chemical cleaners and ultrasonic baths which can exploit feldspar cleavage.

The Natural Gemstone Company stands behind the details provided for this moonstone, and our documentation will include weight, precise measurements, clarity notes, cut description, polish evaluation, enhancement statement noting no treatments, and origin as Ceylon Sri Lanka. We source responsibly and can provide additional provenance information upon request, as well as high resolution images and video to support viewing and selection. For care we suggest cleaning with mild soapy water and a soft brush, storing separately to prevent abrasion with harder gems and metals, and choosing protective mountings for daily wear. If you prefer, we can advise on matching metals and design considerations to highlight the stone s warm brown tone, for example warm gold alloys which complement the brown hue, or mixed metal settings for contemporary contrast.
