0.28 Ct. Moonstone from Ceylon (Sri Lanka)

This listing describes a transparent rainbow moonstone from Ceylon, Sri Lanka, offered by The Natural Gemstone Company, weight 0.28 carat, oval shape, dimensions 4.53 x 3.71 x 3.22 mm, mixed brilliant cut, clarity grade very slightly included evaluated at eye level, light color intensity, excellent polish, no enhancement. The gem displays the characteristic adularescence of rainbow moonstone in a transparent body, and the mixed brilliant cut has been executed to optimize light return and the quality of the schiller. The combination of precise dimensions and measured carat weight confirms that this is a naturally formed, unenhanced specimen, and the excellent polish supports fine surface finish and optical performance. The origin Ceylon, Sri Lanka, is noted for producing moonstones with refined transparency and attractive optical phenomena.

The carat weight of 0.28 is an essential determinant of this moonstones market position and rarity profile. Carat weight remains the standard measure of a gemstones mass, and for moonstone, weight must be considered alongside transparency, optical effect, and cut. A transparent rainbow moonstone at 0.28 carat occupies a distinct segment of the market where small scale is offset by superior material qualities. In practical terms, smaller stones that retain transparency and clear adularescence command a premium on a per carat basis relative to larger stones that are included or cloudy. The rarity in this instance is driven by the convergence of a fine degree of translucence and a clean eye level clarity, each of which becomes statistically less common as transparency improves in this species. Therefore, the 0.28 carat weight, while modest in absolute terms, carries increased relative value because it represents a high quality example within a category where such specimens are scarce.

Beyond the intrinsic weight related value, the physical dimensions and the mixed brilliant cut contribute directly to the perceived size and presence of the 0.28 carat stone. The oval outline at 4.53 x 3.71 x 3.22 mm is proportioned to preserve optical depth while minimizing wasted material, and the mixed brilliant facet arrangement is intended to balance adularescent flash with overall brightness. Excellent polish ensures that surface reflections do not mask the internal sheen, and the very slightly included clarity grade evaluated at eye level indicates that inclusions, where present, do not materially interfere with the gem's visual effect under normal viewing conditions. These factors operate in tandem with carat weight to influence both market valuation and collector interest, because buyers seeking premium rainbow moonstone prioritize a clean, well cut, and well finished stone, even when the carat weight is on the smaller side.

In terms of use and settings, a 0.28 carat transparent rainbow moonstone with these dimensions is well suited to finer jewelry applications where optical quality is the principal design objective. The modest mass allows for integration as a focal accent in a delicate engagement style ring, a refined pendant, or as a contrasting center in multi stone compositions. The dimensions lend themselves to secure bezel or claw settings that preserve the stones optical contribution without exposing it to unnecessary risk, and the lack of enhancement preserves natural color and structure for long term stability. From the perspective of pairing, matching multiple stones of comparable weight and quality for symmetrical designs is feasible but becomes progressively more difficult and costly as transparency and clarity increase, which reinforces the relative rarity of matched sets at this grade and weight.

The Natural Gemstone Company provides this technical profile as part of a transparent record of the gem attributes, weight 0.28 carat being emphasized as a central factor in valuation and rarity assessment. The gems provenance from Ceylon, Sri Lanka, its unenhanced state, mixed brilliant cut, very slightly included clarity at eye level, light color intensity, and excellent polish together define its market position as a small but premium rainbow moonstone. For those evaluating moonstones on the basis of optical performance and natural quality, this 0.28 carat specimen represents an uncommon intersection of transparency, finish, and classic adularescence, characteristics that materially elevate its value relative to typical stones of similar size but lower optical clarity.
