12.19 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This piece is a translucent green moonstone weighing 12.19 carats, presented in a classic oval outline. The dimensions are 15.91 by 13.79 by 7.65 mm, and the cabochon cut has been executed to emphasize the internal glow and surface smoothness. Clarity has been assessed as very slightly included at eye level, indicating minor internal features that do not detract from the gem when viewed without magnification. The color intensity is light, yielding a delicate pale green tone that reads as serene and understated in a variety of settings. The finish is described as excellent polish, and there has been no enhancement applied to alter the natural appearance. The specimen originates from Ceylon Sri Lanka, a source noted for producing moonstones with refined color and stable optical character.

The cabochon shaping of this oval moonstone is central to its optical performance, concentrating the adularescent shimmer that defines the species and translating it into a soft, broad flash across the dome. The symmetry of the oval outline and the careful control of dome height provide a balanced presentation, allowing light to interact with the internal structure evenly across the face. Proportions are consistent, with a depth that translates to approximately 51.5 percent when considered against the mean of length and width, which supports an impressive presence without appearing overly bulky. The polish quality enhances surface reflectivity and preserves clean, crisp highlights, which together with the stone translucence creates the impression of depth and inner luminosity. These attributes combine to produce a level of brilliance and visual focus that positions the gem as a natural centerpiece in a curated collection.

Beyond aesthetics, this green moonstone is suitable for fine jewelry applications that can protect and showcase its qualities. The cabochon form and light green hue make it particularly well suited to bezel or semi bezel settings which can provide security while allowing the dome to remain the visual focus. As a feldspar mineral with a Mohs hardness in the range of six to six and a half, it benefits from settings that mitigate impact and abrasion, and from regular gentle cleaning to maintain surface luster. Collectors and designers will value the unenhanced origin and the documented provenance from Ceylon Sri Lanka, which is associated with a consistent and appealing palette in moonstone material. The Natural Gemstone Company presents this 12.19 carat oval cabochon as a specimen that marries refined cut work and polished finish with natural optical phenomena, an item designed to serve as a prominent focal point in both wearable and cabinet jewelry contexts.
